Automatic registration of high-resolution remote sensing images (HRRSIs) has been a challenging problem due to local deformations caused by different shooting angles and lighting conditions. In order to solve this problem, WIMI has proposed a new method based on feature space object (CSO) extraction and matching. First, the CSO and its localization points on the image are automatically extracted using the Mask R-CNN model. Then, each object and its nearest neighbors are encoded by an encoding method based on object category, relative distance and relative orientation. Next, a code matching algorithm is applied to search for the most similar object pairs. Finally, object pairs are filtered by position matching to construct the final control points for automatic image registration. Experimental results show that the proposed method outperforms traditional optimization methods based on local feature points in terms of registration success rate.
With the continuous development of remote sensing technology, the automatic registration of high-resolution remote sensing images (HRRSIs) has been a serious challenge. Different shooting angles and lighting conditions will cause local deformation of the image, which brings difficulties to data processing and analysis. It is reported that WIMI has launched a high-resolution image automatic registration technology based on feature space objects. Provide reliable information support in areas such as monitoring, urban planning, and agricultural management.
The core of this technological innovation is an automatic registration method based on feature-space objects (CSO). Traditional image registration methods usually rely on grayscale registration, transform domain registration or feature point-based registration, but these methods are very sensitive to grayscale, rotation and deformation, and are computationally intensive, making them unsuitable for automatic registration. WIMI holographic technology adopts a brand-new idea, and achieves more accurate registration results by using the Mask R-CNN model to automatically extract CSO and locate its position.
First, the image is scanned using the Mask R-CNN model, and the CSO and its positioning points on the image are automatically extracted. The accuracy and efficiency of this step is based on the accumulation of research and innovation in the field of computer vision by the WIMI Holographic team for many years. Subsequently, each extracted CSO and its nearest neighbors are encoded according to object category, relative distance and relative orientation. The encoded feature vectors provide the basis for subsequent matching.
In order to find the most similar object pair, WIMI Hologram adopts advanced code matching algorithm. The algorithm determines the degree of matching by calculating the similarity between encoded feature vectors. Object pairs with higher similarities are considered as candidates for registration. Further, the initial object pairs are filtered by position matching algorithm to exclude some false matches and obtain more reliable registration results. Through this step, WIMI holographic technology can accurately capture the spatial position relationship in the image, further improving the accuracy and robustness of registration.
According to the data, WIMI's high-resolution image automatic registration technology based on feature space objects has achieved remarkable results in experiments. By testing and comparing multiple data sets, the results show that this technique is significantly better than the traditional optimization method based on local feature points in terms of registration success rate. [color=green]This breakthrough achievement will enable the remote sensing industry to perform data processing and analysis more accurately and efficiently, providing a more reliable basis for decision-making.[/color]
In addition to remote sensing image processing, this technology also has a wide range of application prospects. In the field of urban planning, automatic registration technology based on characteristic spatial objects can help planners better understand urban changes and development trends, so as to formulate more scientific urban development strategies. In terms of environmental monitoring, this technology can provide accurate image registration results, help scientists monitor and evaluate environmental changes, and provide important data support for environmental protection and resource management. In addition, in areas such as agricultural management and disaster monitoring, this technology can also play an important role, providing accurate data analysis and decision support.
At present, WIMI holographic has introduced the high-resolution image automatic registration technology based on feature space objects to the market, and is exploring application scenarios with industry partners. By integrating this technology with existing remote sensing data processing platforms and software, users will be able to easily achieve high-precision image registration, thereby improving the accuracy and efficiency of data analysis. The introduction of high-resolution image automatic registration technology based on feature space objects marks another important breakthrough of WIMI in the field of image processing. The application of this technology will have a huge impact on the remote sensing industry. In the past, image registration required a lot of time and labor, and the results were not necessarily accurate. However, WIMI holographic technology will make the registration process more automated, efficient and accurate, greatly improving the processing efficiency and quality of remote sensing data.
It can be said that WIMI based on the high-resolution image automatic registration technology of feature space objects has solved the long-standing problems in the field of remote sensing image processing. The application of this technology will provide a more reliable and accurate data basis for scientific research and practice in related fields. In addition, WIMI also plans to carry out further research and development work with industry partners. They will work on further optimizing the efficiency and performance of the algorithm, expanding the scope of application of the technology, and developing more application solutions for different fields.

After years of development, AR has been applied in many fields, such as the introduction of AR filter by Snapchat (SNAP), which adds a new possibility for social entertainment; Baidu (BIDU) map has created a new model of AR innovation and launched the “walking AR navigation” function.
With the continuous improvement of AR technology, a series of new technologies and new trends have emerged and attracted wide attention. For example, AR has also shown great development potential in the automotive field. The emergence of AR-HUD has taken the car driving experience to a new level.
HUD originated in the aviation field, and GM first applied HUD in the automotive field in 1988. As the name suggests, HUD is the projection of important driving information such as speed and navigation onto the windshield, so that the driver can need to see the vehicle information without bowing his head. Its obvious features can better guarantee driving safety. With the update and iteration of the intelligent cockpit, HUD is expected to develop into the core component of intelligent cars with its excellent interactive features of “people and car, people and environment”.
AR-HUD integrates AR function based on HUD, covering a layer of digital images in the real world seen by driving so that the information projected by HUD is integrated with the real driving environment. With the continuous progress of science and technology, more and more automobile manufacturers begin to pay attention to the human-car interaction experience, making the automobile AR-HUD begin to carry richer and more delicate functions and display tasks.
On-board HUD is divided into three main categories
The onboard HUD has experienced three generations of upgrades, continuously optimized imaging quality, continuous increase of information, and greatly enhanced the sense of technology. At present, W-HUD is the mainstream in the market, and AR-HUD is accelerated for mass production.
The first generation is the C-HUD (Combiner HUD), a combined head-up display system. C-HUD uses translucent resin board as the display medium, which has the advantage of convenient installation, but the imaging area is small and the display information is less. Because C-HUD is installed on the vehicle in the form of accessories, it is easy to cause secondary injury to the driver in case of an accident.
The second generation W-HUD (Windshield HUD) windshield head-up display system, which is currently the most widely used HUD, has achieved mass production. The W-HUD uses optical reflection to project driving information onto the front windshield of the car. W-HUD shows a larger range and further projection distance than C-HUD.
The third generation AR-HUD (Augmented Reality HUD) augmented reality head-up display system is a new head-up display technology. Compared with the traditional W-HUD, AR-HUD has a large projection range and more information, which can better combine the data collected by ADAS for scene fusion. Through the superposition of digital images and real scenes, it can enhance the sense of practicality and technology of HUD.
In 2020, the market began to accelerate the iteration of W-HUD to AR-HUD. Because AR-HUD displays increased information compared to W-HUD. AR-HUD collects the data of the external environment through the front-facing radar and camera equipment, calculates the required image and data information through the AR algorithm, and then reflects the image to the windshield through the optical structure in the AR-HUD, and produces a virtual image superimposed on the real object in front of the windshield.
There is no doubt that, as one of the representative features of the intelligent cockpit, AR-HUD is expected to become the final form of HUD in future vehicles. AR-HUD technology has been attracting the attention of the industry. Some institutions expect that the market size of China’s AR-HUD industry will exceed 7 billion yuan in 2023.
Technology is a solid barrier to WiMi
On the eve of the market explosion of AR-HUD, it is reported that WiMi Hologram Cloud (NASDAQ: WIMI) is working on building AR-HUD-related products. Its light field AR-HUD has multi-faceted optical imaging capabilities, which can achieve a better AR fusion effect and a more natural visual experience. In addition, WiMi Hologram Cloud technology solutions are in rapid progress, with uHD key capabilities, to provide rich application scenarios such as instrument information display, AR navigation, safety-assisted driving, night vision/rain and fog enhancement tips, and audio and video entertainment. Project virtual images in different locations in the real world, so that real objects in different positions can visually integrate with HUD virtual images, and may become a dark horse on the track in the future.
WiMi Hologram Cloud As a leading holographic AR application technology provider, fully aware based on AR-HUD technology is gradually become the focus of auto manufacturers, years committed to through independent innovation, positive research, and development, through AR-HUD transmission to holographic AR image display various digital information, an intuitive way to guide driving, improve the intelligent experience, make AR-HUD intelligent cockpit interactive hub, to improve the safety of driving, to help reduce the risk of accident.
With the further development of AR technology, WiMi Hologram Cloud will focus on the core capability of “visual interaction” in the future, while consolidating the dominant position in the field of intelligent automotive electronics and gradually developing products with technological technology such as AR-HUD. It can be said that this is an effort and attempt in emerging industries such as autonomous driving. It is expected to form a perfect human, car, road, and network ecology, and open up a new entrance for the next generation of augmented reality Internet. In addition, WiMi Hologram Cloud will continue to focus on related fields and technologies, and further participate in the larger holographic AR industry track.
To Sum Up
The HUD market is facing a period of rapid development, and many research institutions have given the same view. On-board HUD technology has become an important trend in the automotive industry. Through HUD technology, drivers can get more driving information while maintaining attention and concentration on the road, thus improving driving safety and comfort. With the development and application of AR technology, it is believed that the AR-HUD system can be said to be a major trend in the development of intelligent vehicles in the future, and its addition also makes us full of expectations for future cars.
At present, some people point out that AR-HUD is only a transitional technology to achieve fully autonomous driving in the future. After all, after the realization of autonomous driving, the convenience of AR-HUD head display is also insignificant for users.

With the rapid development of technologies such as Industry 4.0, CPS (Cyber-Physical System), blockchain, cloud computing, and big data, and the rapid development of today's network and information security, access control has become the key for enterprises to protect data and resource security. The essential. In the context of ever-increasing security requirements for network and information systems, access control plays an important role in the field of network and information security as well as interdisciplinary topics in the Internet of Things. XACML (Extensible Access Control Markup Language) is a standard widely used in the field of access control. When the defined policy set becomes large and complex, the policy evaluation time will increase significantly, and the traditional policy evaluation methods often face performance bottlenecks. Performance for large-scale systems is a challenge. In order to solve this problem, WIMI (NASDAQ: WIMI) has developed DPCEngine, which is an efficient density peak clustering algorithm for improving the performance of strategy evaluation.
It is reported that WIMI WIMI Hologram Institute proposed a policy set clustering method based on the density peak clustering algorithm, which reduces the complexity of policy evaluation by identifying the cluster structure in the policy set. The architecture and algorithm flow of WIMI DPCEngine include key steps such as data preprocessing, density peak clustering, strategy matching and evaluation.
To evaluate the performance and effectiveness of DPCEngine, a real dataset containing a large-scale complex policy set is used for experiments. This dataset contains policies from different domains, covering a variety of access control scenarios. The data set is divided into training set and test set, where the training set is used to build the model of DPCEngine, and the test set is used to evaluate its performance.
WIMI Hologram R&D staff compared DPCEngine with traditional strategy evaluation methods, including methods based on linear search and tree structure.
Two performance metrics are evaluated:
- policy evaluation time and
- matching accuracy.
Policy evaluation time refers to the time required to evaluate an access request, while matching accuracy refers to the consistency between the matching results of DPCEngine and traditional methods.
DPCEngine has a significant performance advantage in policy evaluation time. Compared with traditional methods, DPCEngine can greatly reduce the policy evaluation time, especially when the policy set is large in scale and high in complexity. This is due to the density-peak-based clustering algorithm adopted by DPCEngine, which is able to cluster policy sets into smaller subsets, thereby reducing the search space for evaluation.
In terms of matching accuracy of WIMI's DPCEngine, the experimental results show that there is a high consistency between the matching results of DPCEngine and traditional methods. This shows that DPCEngine does not sacrifice accuracy while improving policy evaluation performance. In addition, we also conducted scalability experiments to evaluate the performance of DPCEngine under different scale policy sets. The results show that DPCEngine can effectively cope with large-scale policy sets and has good scalability. Its working process is shown in the figure.
According to the data, WIMI's DPCEngine, as a strategy evaluation engine based on the density peak clustering algorithm,
has three main functions:
- preprocessing strategy set,
- cluster strategy set and
- matching strategy.
The combined use of these functions can significantly improve the performance and accuracy of policy evaluation.
Preprocessing strategy set:
Before policy evaluation, DPCEngine prepares data by preprocessing strategy sets, making it more suitable for density peak clustering. The preprocessing process includes steps such as data cleaning, feature extraction and data conversion. Ensure data accuracy and consistency by cleaning data to remove redundant, incomplete or erroneous policy information. Avoid negatively affecting the assessment results. The feature extraction process extracts key features from the policy set, such as user roles, resource types, and operation permissions, for subsequent clustering operations. Data transformation converts the strategy set into a data representation suitable for the density peak clustering algorithm, such as a vector or matrix, for cluster analysis.
Cluster policy set:
DPCEngine uses the density peak clustering algorithm to perform cluster operations on the policy set. The density peak clustering algorithm identifies the cluster structure in the policy set by evaluating the density and distance between the policies. The algorithm determines the peak point based on the density and distance between the policies, and divides the policies between the peak points into different clusters . This enables the clustering of a large and complex set of policies into smaller subsets, each cluster representing a set of policies with similar characteristics and behavioral patterns, reducing the time and complexity of policy evaluation. The result of the cluster strategy set is a group of strategy clusters with similar characteristics and behavior patterns. This cluster strategy set method can reduce the time and computational complexity of strategy evaluation, and improve the performance and efficiency of the system.
Matching strategy:
DPCEngine uses clustering results for strategy matching. When an access request arrives, DPCEngine compares and matches it with the pre-generated policy cluster. By searching for the most similar policy in each cluster, DPCEngine can quickly determine the policy set that matches the access request. This clustering-based matching method can significantly speed up policy matching and provide accurate matching results. In addition, DPCEngine can also combine other access control technologies and rule engines to further optimize the policy matching process to ensure system security and compliance.
Through the comprehensive use of preprocessing policy sets, cluster policy sets and matching policies, DPCEngine can provide enterprises with efficient and accurate policy evaluation.
In addition, WIMI's (NASDAQ: WIMI) DPCEngine's preprocessing policy set, cluster policy set and matching policy functions cooperate with each other to provide enterprises with an efficient, accurate and scalable policy evaluation performance. By utilizing the density peak clustering algorithm and the clustering structure of policy sets, DPCEngine can achieve fast policy matching in the case of large-scale complex policy sets. This cluster-based approach reduces the time and computational complexity of policy evaluation and improves the performance and efficiency of the system.
The three main functions of DPCEngine have broad application prospects in enterprises.
- First, the preprocessing policy set function can help enterprises process and prepare huge policy data to ensure data quality and consistency. This is crucial for cleaning and transforming the data prior to policy evaluation to improve the accuracy of subsequent clustering and matching.
- Second, the Cluster Policy Set feature enables enterprises to divide large and complex policy sets into relatively smaller policy clusters with similar characteristics. This cluster operation reduces the size and complexity of policy evaluation and improves the performance and efficiency of the system. By grouping similar policies together, enterprises can match access requests more quickly and implement fine-grained management and control over policies.
- Finally, the Match Policy feature allows organizations to compare and match access requests against pre-generated policy clusters. This clustering-based matching method can quickly locate the policy set that matches the access request, improving the speed and accuracy of policy matching. At the same time, DPCEngine can be used in combination with other access control technologies and rule engines to further optimize policy matching results and ensure system security and compliance.
Currently, the preprocessing policy set, cluster policy set and matching policy functions of WIMI DPCEngine enable enterprises to efficiently evaluate access control policies. This policy evaluation engine based on the density peak clustering algorithm has broad application prospects in various industries and fields, and can help enterprises build a robust security protection system and cope with growing security challenges. With the continuous development and improvement of technology, DPCEngine will further improve the performance and accuracy of policy evaluation, and provide reliable support for enterprises to ensure the security of data and resources.
WIMI (NASDAQ: WIMI) Releases Brain-Computer Interface (BCI) Encrypted Anonymizer Software Technology System.

Brain-computer interface technology is a cutting-edge technology with great prospects and a broad market application base.
It has unique advantages:
it can access the neural data decoded by the brain in real time. Even sports and other activities are combined to carry out neuromodulation technology. With the rapid development of technology, mobile technology, communication and cloud computing, the brain-computer interface technology has developed rapidly, enabling us to explore things that were unimaginable a few years ago. Application scenarios, the development far exceeds expectations. Currently there are business-oriented (B2B) devices on the market, and consumer-oriented (B2C) commercial devices. Although the development of brain-computer interface technology has brought many opportunities and application prospects, it also brings Here comes some security and privacy concerns.
According to reports, in order to ensure the security and privacy protection of brain-computer interface technology, WIMI (NASDAQ: WIMI) is developing a software system brain-computer interface encrypted anonymizer to ensure user information security and privacy issues.
Brain-computer interface (BCI) technology represents a direct communication link between the brain and external devices. Recent findings demonstrate how electroencephalography (EEG) signals recorded from consumer-grade BCI devices can be used to extract private information about users. With enough computing power, this information can be used by others to infer our memories, intentions, conscious and unconscious interests, and our emotional responses.
This technology has a wide range of applications, from medical devices to gaming and entertainment. However, the use of BCIs raises security and privacy concerns because EEG signals can reveal sensitive information about a user's thoughts, emotions, and memories. Therefore, it is critical to develop techniques that ensure the privacy and security of BCI users.
Research on improving the privacy and security properties of BCI-enabled technologies involves two major steps.
The first step focuses on identifying which components of electroencephalography (EEG) signals can be used to extract private information. After identifying potential vulnerabilities, WIMI's R&D team will quantify the amount of information exposed. Based on the results obtained,
the second step was the development of software encryption tools designed to prevent the possible extraction of users' private information. The "BCI encrypted anonymizer" developed by WIMI is based on signal components, that is, the recorded brain signals can be decomposed into a collection of characteristic signal components in real time. From these components, information corresponding to the user's expected BCI commands can be extracted while filtering out potentially private information.
EEG signals are a combination of different frequencies, each with unique characteristics. The EEG signal components used for private information extraction, the EEG signal components most susceptible to private information extraction are alpha waves and beta waves. Alpha waves are associated with relaxation, while beta waves are associated with cognitive processing and attention. Thus, alpha and beta waves can reveal sensitive information about a user's emotional state, cognitive ability, and attention span.
In order to quantify the amount of information that can be extracted from EEG signals, WIMI WIMI will use the mutual information (MI) method. MI measures the amount of information shared by two variables. In this case, WIMI's R&D team will measure the MI between the EEG signal and the private information that can be extracted from it. Based on MI results, the risk level of extracting private information from EEG signals can be determined.
The BCI encrypted anonymizer developed by WIMI Hologram is a software tool that can prevent the extraction of private information from EEG signals. The tool works by decomposing the EEG signal into a set of characteristic signal components. These components are the building blocks of the EEG signal and can be used to reconstruct the original signal. However, BCI anonymizers filter out components that contain private information, allowing only those needed to control external devices. This technology aims to strengthen the development of closed-loop brain-controlled interfaces, so as to better protect the privacy and security of users. We believe that this technology will provide a safer and more reliable option for future BCI applications.
The brain-computer interface encrypted anonymizer released by WIMI (NASDAQ: WIMI) works in real time without any additional hardware or sensors. It can be integrated into existing BCI systems and customized for different applications. The tool can also be used for offline data analysis to identify potential privacy risks in existing BCI data.
The privacy and security of brain-computer interface technology is critical to ensuring the trust and acceptance of the technology by users in its future development. WIMI's technical solutions can help address security and privacy concerns by identifying EEG signal components that are susceptible to private information extraction and developing software tools to prevent their extraction. The encrypted anonymizer of brain-computer interface can improve the privacy and security of users without compromising the function of brain-computer interface system. This technology could lead to the development of more advanced brain-computer interface systems that provide real-time control of external devices without compromising user privacy. This technical solution can effectively improve the security and reliability of brain-computer interface devices, avoid data leakage and abuse, and provide better user experience and services.

In recent years, with the continuous development and application of artificial intelligence technology, image classification technology has been widely used in many fields. And with the rise of deep learning, convolutional neural network (CNN) has become the mainstream model for processing image classification tasks. CNNs recognize images by automatically extracting features from them, and classify them using the softmax function. However, due to the limitations of the softmax function, traditional CNN models have some deficiencies in image classification.
It is reported that in order to solve this problem, WIMI has developed a new image classification method that uses a hierarchical structure inspired by the animal visual system to automatically extract features from images. This method combines bionic pattern recognition (BPR) with CNN, which can make full use of the geometric structure of high-dimensional feature space, so as to achieve better classification performance, so it can overcome some shortcomings of traditional pattern recognition. The method has been validated in multiple experiments and, in most cases, achieves higher classification performance than traditional methods.
A Convolutional Neural Network (CNN) is a deep learning model specifically designed to process images. It can automatically extract features from images through convolution and pooling operations, and use fully connected layers for classification. The convolution operation refers to applying a convolution kernel (also known as a filter) to each location on the image and outputting the result as a feature map. The pooling operation refers to downsampling on the feature map to reduce the amount of computation and the risk of overfitting.
In the traditional CNN image recognition classification model, the softmax function is used for classification. The softmax function can convert a set of scores into a probability distribution, where each score represents a confidence score that the image belongs to a certain class. Traditional pattern recognition methods usually use hyperplanes in feature space to segment categories. However, this method has some disadvantages, such as requiring manual feature selection and difficulty in handling nonlinear data. In contrast, bioinspired pattern recognition (BPR) can overcome these problems by performing class recognition on geometric cover sets that are unioned in a high-dimensional feature space.
BPR is a pattern recognition method based on bionics.
Its basic idea is to use biological systems to simulate the processing of sensory information, and regard the pattern recognition process as being carried out in a high-dimensional feature space. In this high-dimensional space, each sample point is regarded as an object rather than a point. Therefore, samples of different classes are distributed in different regions in the high-dimensional feature space, and these regions are called geometric covering sets. Each geometry cover set consists of a set of geometric objects called geometric primitives, such as spheres, cones, polyhedra, etc. With a proper combination of geometric primitives, a coverage set with high classification performance can be constructed to achieve class recognition.
Research shows that WIMI combines BPR and CNN to achieve better image classification effect. Specifically, based on bionic pattern recognition (BPR) convolutional neural network (CNN) image classification, CNN features can be mapped into a high-dimensional feature space, and a geometric coverage set can be constructed in this space, and then the new sample map Go into that space and decide what category it belongs to.
According to the data, WIMI uses a mapping function to map CNN features into a high-dimensional feature space in BPR-based CNN image classification. This mapping function can be a simple nonlinear transformation such as a polynomial transformation or a radial basis function (RBF) transformation. It is also possible to use some more complex function, such as a neural network or a support vector machine (SVM), to learn this mapping function, converting the CNN features into a form that is easier to classify in a high-dimensional feature space.
WIMI Holographic CNN-BPR image classification technology uses proven geometric primitives with high classification performance in high-dimensional feature spaces, such as spheres, cones or polyhedrons, to construct geometric coverage sets. Then, we can use some optimization algorithm, such as genetic algorithm or particle swarm optimization algorithm, to search for the optimal combination of geometric primitives to construct the optimal geometric cover set. Finally, we can use a classifier, such as the K-Nearest Neighbors algorithm or a Support Vector Machine (SVM), to identify the class to which the new sample belongs.
The specific way to realize the image classification method combining BPR and CNN is as follows:
Prepare training and test datasets:
You need to collect a dataset that contains images of many different categories.
This dataset should consist of two parts:
a training dataset and a testing dataset. The training data set is used to train the CNN model, and the test data set is used to test the performance of the classifier.
Train the CNN model to extract image features:
Use the training dataset to train the CNN model and use the model to extract the features of each image. These features will be used to construct a geometric cover set in a high-dimensional feature space.
Mapping CNN features into a high-dimensional feature space:
A mapping function needs to be used to map CNN features into a high-dimensional feature space. This mapping function can be learned using some nonlinear transformation, such as polynomial transformation or RBF transformation, or using more complex functions, such as neural network or SVM.
Build a geometric cover set:
Use some geometric primitives that have been proven to have high classification performance in high-dimensional feature spaces, such as spheres, cones, or polyhedra, to build geometric cover sets. Then, we can use some optimization algorithm, such as genetic algorithm or particle swarm optimization algorithm, to search for the optimal combination of geometric primitives to construct the optimal geometric cover set.
Classify new samples:
Finally, use a classifier, such as K-Nearest Neighbors or SVM, to identify the class to which the new samples belong. We can map the features of a new sample into a high-dimensional feature space, then find the nearest geometric cover set in this space, and finally classify the new sample into the category represented by the cover set.
In addition, WIMI's CNN-BPR image classification technology features a combination of convolutional neural network and bionic pattern recognition, and performs image classification by constructing a geometric coverage set in a high-dimensional feature space. Compared with the current traditional CNN model that uses the softmax function for classification, the softmax function has limited capacity and cannot handle complex classification problems well, such as image classification. In addition, CNN models cannot fully exploit the geometric structure of high-dimensional feature spaces, thus failing to achieve optimal classification performance. And traditional pattern recognition methods usually need to manually select features and classifiers, requiring a lot of manpower and time costs.
By combining BPR and CNN, this technology can overcome some shortcomings of traditional pattern recognition, improve the performance of image classification, and can handle complex image classification problems. This method can overcome some shortcomings of the current traditional pattern recognition in image classification and in most cases, it has higher classification performance than traditional methods. And it can handle complex image classification problems, such as image recognition, object detection and image segmentation.
At present, image classification technology based on convolutional neural network has been widely used in many fields. The method of WIMI hologram combined with bionic pattern recognition can overcome the limitations of traditional pattern recognition methods and improve the accuracy and reliability of image classification. It is believed that with the continuous development and progress of technology, this technology will have wider application and better performance in the future.

Last week, Tesla CEO Elon Musk tweeted that the brain-computer interface could solve the biggest bottleneck in human progress. As we all know, Musk launched Neuralink in 2016. He believes that the company's technology can help humans and artificial intelligence achieve a "symbiotic" state. Simply put, people will be able to integrate their brains with computers effortlessly.
When it comes to brain-computer interfaces, the first impression in everyone's mind may be the scene where Musk lets monkeys realize "idea typing". Since then, Musk's Neuralink has been developing brain implants aimed at treating paralysis and blindness, etc. disease. However, what surprised the outside world recently is the team from China.
The world's first "Monkey Brother" interventional brain-computer interface test was successful
Recently, the world's first non-human primate interventional brain-computer interface test was successful in Beijing, which is of great significance to promoting research in the field of brain science and marks that my country's brain-computer interface technology has become an international leader.
The experiment was led by the team of Professor Duan Feng of Nankai University, jointly completed with the General Hospital of the Chinese People's Liberation Army (301 Hospital) and Shanghai Xinwei Medical Technology Co., Ltd., which made breakthroughs in intravascular EEG signal acquisition and interventional EEG signal recognition. Core Technology. Judging from the video data, the post-operative monkey only needs to "think about it" before it can let the robotic arm deliver food into its mouth.
This technology has a wide range of applications in medical, military and other fields. For example, it can help patients with stroke and frostbite recover, and it can even store human thinking, consciousness, and memory in the future. This series of results that sound amazing has already begun to be realized. It seems that the scenes in some sci-fi blockbusters are not so far away from us.
Brain-computer interface refers to the direct connection created between the human or animal brain and external equipment to realize the information exchange between the brain and the equipment.
At present, there are three main types of brain-computer interface, including:
- invasive brain-computer interface,
- non-invasive brain-computer interface and
- interventional brain-computer interface.
Neuralink, founded by "Silicon Valley Iron Man" Musk and a team of scientists, is a representative of a small number of companies engaged in the development of invasive brain-computer interfaces.
In contrast, the interventional brain-computer interface technology used in the Chinese trial is safer. According to the information released by Nankai University, the research team let the interventional EEG sensor pass through the monkey's jugular vein, enter the sagittal sinus, and reach the monkey's motor cortex brain area. After the operation, the team successfully collected and recognized the interventional EEG signals of non-human primates, realizing the active control of the mechanical arm by the animals.
It can be said that the interventional brain-computer interface takes the advantages of both invasive and non-invasive at the same time, while avoiding the disadvantages of both. Judging from the current development, brain-computer interface technology has continuously made breakthroughs, which may first benefit the medical industry. Guotai Junan Securities pointed out that medical health is the main application scenario of brain-computer, and it will gradually penetrate into entertainment, smart home and other fields in the future, becoming an important form of human-computer interaction.
Brain-computer interface technology will empower the metaverse
Brain-computer interface is a complex system and a basic tool for reading and writing neuron dynamic network data. What is even more surprising is that with the sudden emergence of the Metaverse, people have great expectations for the integration and interaction of the virtual world and the real world. Many people in the industry believe that the brain-computer interface is a cutting-edge technology hatched by the Metaverse.
In the future, the brain-computer interface technology will empower the metaverse, and the brain-computer interface is expected to become the next generation of human-computer interaction technology and the ultimate form of the metaverse. At the same time, with the continuous development of the Metaverse, the strong support of national policies, and the continuous exploration of brain science, the brain-computer interface will become the entrance of the next generation of Metaverse after VR and AR, realizing the real Metaverse.
According to the "White Paper on Brain-Computer Interface Standardization" released by the China Electronics Standardization Institute, the potential market for Brain Computer Interface (BCI) technology will soon reach tens of billions of dollars. Another predictive analysis believes that in the next 20-30 years, the commercial application of brain-computer interface will gradually land, which will open up a market worth hundreds of billions of dollars.
The technological race has already begun. Brain-computer interface technology is an important strategic direction for a new round of scientific and technological revolution and industrial transformation. The future industry represented by brain-computer interface has already entered the fast lane, and the formation of breakthrough scientific research results and innovative applications is a strategic need for innovative development.
WIMI Hologram focuses on the field of brain-computer interface and has made great achievements
At present, the field of brain-computer interface has tried to integrate technology in the consumer field, and its application in game interaction is becoming more and more popular. It is understood that WIMI (NASDAQ: WIMI) has started to develop the BCI game model and paradigm based on the brain-computer interface. A game model is designed with a P300 brain-computer interface to explore a feasible and natural game execution experience using electroencephalography (EEG) signals in a real-world environment.
According to reports, the novelty of WIMI's research is reflected in the design of the BCI game and paradigm, which integrates the game rules and the characteristics of the BCI system. In addition, a convolutional neural network (CNN) algorithm is introduced to achieve high accuracy on training samples. This brain-computer interface system not only provides users with a form of entertainment, but also provides more manipulation possibilities for games.
To be sure, WIMI is based on the CNN BCI game model, forming a platform that can satisfy the interests of both healthy and disabled users. For healthy users, brain-computer interface games are mysterious and technical, which increases the charm of the game and is very conducive to the promotion of the game. For disabled users, BCI games provide them with a fair gaming platform, not only allowing them to play games in the same way as healthy users, but also as a functional rehabilitation system to help patients with rehabilitation training. Obviously, WIMI's application of brain-computer interface technology to entertainment games is an important part of promoting BCI technology from the scientific research stage to the actual application market stage.

With the continuous development and application of blockchain technology, the blockchain-based business process management system (BPMS) has gradually become an important part of the digital transformation of enterprises, and more and more enterprises have begun to adopt blockchain in their business process environment chain technology to improve the efficiency and security of its business processes. Blockchain-based business process management systems (BPMS) have become an integral part of this trend.
However, due to the complex requirements for data security and privacy in practice, no single blockchain can capture all use cases. The coexistence of blockchains optimized for various risk tolerances and confidentiality in a multi-chain environment poses serious architectural challenges for blockchain-based business process management systems (BPMS). In order to solve these problems, WIMI (NASDAQ: WIMI) has developed a general architecture for blockchain-based business process management system (BPMS) to support orchestrated multi-chain BPMS.
1. An overview of the general architecture of WIMI's blockchain-based business process management system (BPMS).
Blockchain-based business process management system (BPMS) refers to the management and orchestration of internal or cross-enterprise business processes through blockchain technology, thereby improving the efficiency and security of business processes.
Generally, a blockchain-based BPMS includes the following components:
- On-Chain Protocol,
- Off-Chain Protocol,
- Smart Contract and
- Business Process Orchestration.
However, due to the various complex requirements and constraints of different business processes and environments, no single blockchain can meet all needs. Therefore, WIMI Hologram has developed a general architecture to support orchestrated multi-chain BPMS, which can adapt to different business processes and environments while ensuring data security and privacy protection.
2. The architecture design of WIMI holographic multi-chain environment.
In a multi-chain environment, we need a flexible architecture to support different business processes and environments. To this end, we propose a multi-chain architecture based on process orchestration, which consists of three main components: a business process management system (BPMS) orchestration engine, a blockchain integration layer, and a smart contract layer.
1. Business process management system (BPMS) orchestration engine
The business process management system (BPMS) orchestration engine is the core component of the multi-chain BPMS, which is responsible for mapping business processes to blockchains and integrating different blockchains into the same business process. In the implementation, we use a model based on graph theory to describe business processes to support complex business processes and interactions between processes.
The BPMS orchestration engine provides the following functions:
Visually design and edit business processes:
Support users to use a graphical interface to design and edit business processes, including defining process nodes, transition conditions, and business rules.
Blockchain integration management:
support the integration of different types of blockchains, and provide related interfaces and tools to directly call the functions of blockchains in business processes.
Interaction coordination:
Support interaction and coordination between different business processes to achieve cross-chain transactions and cooperation.
2. Blockchain integration layer
The blockchain integration layer is a bridge connecting the BPMS orchestration engine and the underlying blockchain, which provides interfaces and tools for interacting with different blockchains. In the implementation, we use standardized interface protocols, such as RESTful API, WebSocket, etc., to ensure the scalability and compatibility of the integration.
The blockchain integration layer provides the following functions:
Blockchain node management:
support connection, configuration and management of different blockchain nodes, including public chains, alliance chains and private chains.
Blockchain interaction interface:
Provide interfaces and tools for interacting with different blockchains, so that the functions of the blockchain can be directly called in the business process, such as querying transaction records, creating transactions, etc.
Blockchain data synchronization:
Supports the synchronization of data on the blockchain to the business process management system to achieve more efficient business processes and data analysis.
3. Smart contract layer
The smart contract layer is the core component of the underlying blockchain, which is responsible for executing and managing contract codes, and provides interfaces and tools for interacting with the blockchain. In the implementation, we use smart contract languages, such as Solidity, Vyper, etc., to realize the writing and deployment of smart contracts.
The smart contract layer provides the following functions:
Contract writing and deployment:
Supports writing and deploying contracts using smart contract languages ??to automate business processes.
Contract execution and management:
responsible for executing and managing smart contracts, and providing interfaces and tools for interacting with the blockchain.
Contract upgrade and expansion:
Support contract upgrade and expansion to adapt to different business needs and environmental changes.
The multi-chain architecture of WIMI (NASDAQ: WIMI) process orchestration can flexibly support different business processes and environments, realize cross-chain transactions and cooperation, and provide standardized interfaces and tools to ensure integrated scalability and compatibility. The orchestration engine is the core of the system and is responsible for managing the entire business process. It can interact with the multi-chain blockchain network through smart contracts and ensure the smooth progress of cross-chain transactions on all chains. The orchestration engine also provides advanced features such as automated process monitoring, error handling, and event notification. It can also integrate with external systems, such as CRM and ERP, to collaborate with a business' existing systems.
3. Advantages of WIMI's blockchain-based business process management system (BPMS) general architecture:
Flexibility:
Since our architecture is based on a multi-chain blockchain network, it can be flexibly configured according to different business needs, such as adjusting block size, confirmation time and number of nodes.
Scalability:
Our architecture can be scaled horizontally to hundreds of nodes, thus supporting larger business scale and higher throughput.
Privacy protection:
Each blockchain can have its own access control and authentication mechanism, as well as private smart contracts, thus providing better privacy protection.
Security:
Transactions between multiple blockchains can be mutually verified, reducing the possibility of attacks.
Transparency:
Every transaction can be verified on multiple chains, providing better transparency.
In this architecture, a multi-chain blockchain network is used, which can provide better scalability because each blockchain can be optimized according to its needs, such as adjusting block size and confirmation time. Second, it can provide better privacy protection, since each blockchain can have its own access control and authentication mechanisms, as well as private smart contracts. It can provide greater security because transactions between multiple blockchains can be mutually verified, reducing the possibility of attacks.
WIMI's (NASDAQ: WIMI) blockchain-based business process management system (BPMS) general architecture can be applied to various industries. For example, modern supply chain management requires a high degree of coordination and cooperation among various players, involving multiple organizations and complex transaction processes. Traditional supply chain management often lacks transparency and data sharing, which can lead to delays, increased costs and trust issues. A blockchain-based BPMS can provide a traceable, immutable, and distributed shared ledger, which can help organizations better manage supply chains, reduce delays and costs, and build trust.
At the same time, through the use of smart contracts, many supply chain processes can be automated, improving efficiency and reducing errors. Another industry pain point is financial services. Blockchain technology can provide a safer, more transparent and more efficient transaction platform, which can help banks and financial institutions reduce operating costs, increase transaction speed and reduce fraud. Through the blockchain-based BPMS, data security and privacy can be ensured, and various financial transactions such as payment, transfer, settlement and asset management can be executed through smart contracts. In conclusion, blockchain-based BPMS can be applied in a variety of different industries and fields, improving data security, transparency and efficiency, and helping organizations better manage complex business processes.

With the development of computer technology, digital signal processing algorithms have been continuously optimized and improved, such as GPU-based efficient algorithms, multi-level parallel processing, etc., which have greatly improved the reconstruction speed of holographic images. Holographic three-dimensional imaging technology has gradually been widely used in medicine, biological science, material science, physics and other fields due to its unique advantages, such as beam navigation, optical micro-imaging, high-resolution micro-imaging, etc.
It is understood that the research and development team of WIMI has developed digital holography and three-dimensional imaging technology, which is a technology that uses laser technology, digital signal processing and other technical means. A new technology for 3D image detection, analysis, recognition and display. It calculates the three-dimensional structure of the object by recording the amplitude and phase of the object in the interference pattern of the object and the reference wave, then uses digital signal processing to convert the interference pattern into a holographic image, and then converts the holographic image into a three-dimensional image through numerical reconstruction processing technology image, so as to realize the three-dimensional image reconstruction of the object.
The basic principle of numerical reconstruction of three-dimensional stereoscopic image by optical scanning hologram developed by WIMI involves optics, interferometry and digital image processing technology. Its technical process includes hologram recording, digital hologram, calculation of reverse transfer function, digital image processing, reconstruction of hologram, etc. Through these steps, a three-dimensional image with high fidelity and realistic feeling can be obtained, which is helpful to better study and display the shape and structure information of the object.
hologram recording
A laser source is used to generate a coherent beam of light, which is then passed through an object, causing the beam to scatter or reflect. The scattered or reflected light is then optically interfered with a reference beam to form an optical hologram.
digital hologram
Digitally scan the optical hologram, and convert the optical hologram into digital information through digital processing. The digitized holographic image is represented by an array of pixels (dot matrix), and the gray value of each pixel is proportional to the density of the ink sheet.
Calculate the back transfer function
Using computer algorithms to calculate the object information stored in the hologram, this process is called calculating the reverse transfer function. The back transfer function refers to the algorithm that derives the original object field from the hologram. The three-dimensional shape information of the object is obtained, that is, the position coordinates of each point in space and the shape of the object.
digital image processing
In the process of digital image processing, it is necessary to pre-process the digital hologram, such as enhancing contrast, reducing noise, etc., in order to improve the quality of the final reconstructed image.
Three-dimensional reconstruction
The processed hologram is converted into a three-dimensional image through a computer algorithm, thereby completing the process of image reconstruction. A technique based on the principle of diffraction, based on the interaction of the calculated inverse transfer function with the wavefront generated by the light source, resulting in a three-dimensional stereoscopic image.
render image
Use computer graphics algorithms to render three-dimensional stereoscopic images into realistic images. The physical properties of light, such as shadows and reflections, can be simulated during rendering.
WIMI's optical scanning hologram numerical reconstruction three-dimensional image technology has a very high resolution and can achieve microscopic imaging. Moreover, the visualization effect is good, not only can intuitively present the three-dimensional shape of the object, but also provide information about the optical properties of the object, which will provide a powerful tool for scientific research. It will be widely used in biology, medicine, material science and other fields, such as three-dimensional microscopic imaging, medical imaging diagnosis, quantitative analysis and quality inspection of materials, etc.
With the increasing demand for 3D information, the 3D imaging technology represented by optical scanning hologram numerical reconstruction technology will gradually become an important basis for 3D vision, AR/VR and other fields. Therefore, the application prospect of this technology will also show a trend of becoming more and more extensive. On the one hand, with the continuous advancement of science and technology, the emergence of new technologies will provide a broad space for the continuous improvement of the technology. At the same time, the technology itself has many fields that can be further cultivated, such as 3D super-resolution microscopic imaging, 3D surface measurement, 3D printing, etc., which have great application potential.
WIMI (NASDAQ: WIMI) develops a log analysis framework for self-driving car test drives.

May 12, 2023
The autonomous vehicle (AV) industry is growing rapidly due to improvements in artificial intelligence (AI) technology based on sensing devices. So far, self-driving cars from as many as dozens of companies are driving on real roads for safety and performance testing. Some of them have driven tens of millions of miles, and even billions of miles in simulation. These car markets contain a large number of data sets, including all sensor data and vehicle driving information, which can be used for deep learning and provided for autonomous driving learning. These datasets include not only the vehicle's position, velocity, acceleration, but also image information obtained from cameras, light detection and ranging (LiDAR) sensors, and GPS. The information is very detailed, including not only the own vehicle, but also the information of the surrounding environment of the vehicle, which is very useful for analyzing autonomous driving problems. However, this data is so large that it takes up a lot of storage space and is difficult to analyze. Therefore, there are difficulties in testing various environments.
Based on this, WIMI (NASDAQ: WIMI) has developed a log analysis framework for autonomous vehicle test drives. Based on a formally-specified logging architecture, the framework can organize logs hierarchically, find out the prior relationships between them, and detect algorithmic or implementation errors. Vehicle logs are an essential source for detecting and analyzing events during driving. However, a set of dumped logs is usually mixed and fragmented because they are generated simultaneously by many modules such as sensors, actuators, and programs. This makes it difficult to analyze them for potential errors that may occur due to the complex chain reaction between these modules. In order to solve this problem, WIMI Hologram proposes a logging architecture based on formal specifications, and organizes the logs hierarchically to find out the prior relationship between them. Algorithmic or implementation errors are detected by examining posterior relationships, while metamorphic tests are employed to quantitatively verify formal specifications to uncover potential conflicts that may exist.
According to the information, the system is a log analysis framework for self-driving car test drives, designed to help discover potential errors that may be caused by complex chain reactions between different modules. A major component of the framework is a formal specification-based logging architecture that organizes logs hierarchically to find out their relationships. By examining these relationships, algorithmic or implementation errors can be detected.
However, testing under certain parameters does not necessarily trigger a potential conflict on the relationship. To remedy this shortcoming, the framework employs metamorphic testing to quantitatively verify the formal specification. This can help locate relationship conflicts and help improve the system. In order to verify the effectiveness of the system, the researchers constructed two experimental environments. One experimental environment is based on simulated driving tests, and the other experimental environment is based on driving log analysis techniques of actual vehicles. Both test environments used the implemented autonomous driving system to evaluate the performance and feasibility of the framework.
At present, the log analysis system of WIMI (NASDAQ:WIMI) self-driving car test drive is a logging framework based on formal specifications, which aims to detect and analyze the basic source of events during driving through the analysis of logs.
The technical logic of the system mainly includes the following steps:
Data collection and preprocessing:
First, the system needs to collect data from various sensors of the self-driving car. These data include the vehicle's position, velocity, attitude, acceleration, sensor data, etc. Since vehicle logs are usually mixed and fragmented since they are generated simultaneously by many modules (such as sensors, actuators, and programs), preprocessing is required for the next step of analysis.
Hierarchical organization of logs:
The system organizes the collected data hierarchically according to formal specifications. This specification includes the formal description of vehicle and environmental parameters, traffic regulations, control algorithms, and the formal definition of the execution process. Through this hierarchical organization, a priori relationship between data can be found, and then algorithm or implementation errors can be detected in subsequent analysis.
Posterior relation detection:
The system detects algorithmic or implementation errors by examining the posterior relation. By analyzing hierarchically organized logs, the system can find a posteriori relationships and detect potential errors by comparing expected and actual outcomes. If there are bugs, the bugs need to be fixed and retested and validated.
Metamorphic tests:
tests performed in the case of certain parameters (so-called oracle tests) do not necessarily trigger potential conflicts on relationships. In systems, this is remedied by employing metamorphic tests to quantitatively verify the formal specification. Variation testing is a systematic approach to varying input data to test the behavior of a system under different conditions. With this approach, the system can more fully verify its formal specification and discover potential errors and flaws.
Application example:
Finally, the market application of the system is mainly for test driving and testing of autonomous vehicles. By using the system, developers can gain a more complete understanding of how autonomous vehicles behave under different conditions and detect potential errors and flaws. This can greatly improve the safety and performance of self-driving cars and promote the development of self-driving car technology.
It can be said that WIMI Hologram provides a novel method to analyze the logs generated during the test drive of self-driving cars and help to find possible errors. It uses advanced logging techniques and testing methods to provide useful tools and techniques for those developing self-driving cars.
For the large amount of data generated when self-driving cars are tested in a real road environment, it needs to be coordinated and analyzed through a certain technical framework. Among them, the key technologies include data acquisition, data storage, data preprocessing, data analysis, etc. First of all, data acquisition requires the acquisition of vehicle driving data through a variety of sensors, including visual sensors, lidar, millimeter-wave radar, inertial navigation systems, etc., to obtain information about the surrounding environment of the vehicle and the state of the vehicle. Second, data storage requires efficient storage and management of acquired data. Distributed file systems and database technologies are usually used to ensure high reliability and scalability of data. At the same time, the data needs to be stored in a certain format to facilitate subsequent data preprocessing and analysis.
Data preprocessing includes data cleaning, denoising and feature extraction. In autonomous vehicle testing, the acquired data is noisy because sensors may be disturbed by various factors. Therefore, it is necessary to denoise the data to ensure the accuracy of subsequent data analysis and visualization. In addition, through feature extraction, key information in the data can be extracted for subsequent data analysis. Data analysis requires the analysis of data through techniques such as machine learning and deep learning. Among them, analysis methods based on statistics, methods based on machine learning and methods based on deep learning are included. Through data analysis, evaluation results on the performance and safety of self-driving cars can be obtained, as well as optimization suggestions. Through the realization of the above technical logic, the test data of self-driving cars can be coordinated and analyzed in an all-round way to provide support for the performance and safety of self-driving cars.
Self-driving cars are an important part of future transportation, and their market prospects are huge. According to market research firm forecasts, by 2025, the global autonomous vehicle market will exceed $200 billion. At present, self-driving car technology has received extensive attention from many automakers and technology companies, including Tesla, Google, Uber, etc. These companies are constantly advancing their self-driving car technology and investing heavily in research and development. WIMI (NASDAQ: WIMI) will also continue to promote the development of software and data analysis technology related to self-driving cars, making contributions to the development of the industry. greater contribution.

After preparing the data of the 3D object and building the model, the next step is to train the deep learning model. Deep learning models are the key technology for converting 3D models into holograms. In this process, we can use deep learning models such as convolutional neural networks (CNN). In the process of model training, a large amount of data needs to be used for training to improve the accuracy and stability of the model.
? Hologram generation
After the training of the deep learning model is completed, the hologram can be generated next. In this process, we need to input the 3D model into the deep learning model, and then render the output into a hologram. During the hologram generation process, it is necessary to pay attention to the setting of the light source and the adjustment of the hologram. These factors affect the visual quality and realism of the resulting hologram.
? Hologram display
Finally, the resulting hologram needs to be displayed. In the process of displaying holograms, light sources and specific projection equipment, such as holographic projectors, are required. During the presentation, it is necessary to pay attention to the position of the light source and the intensity of the light, as well as the setting and calibration of the projection equipment. These factors affect the look and feel and clarity of the final hologram.
