Motion vector prediction and refinement using candidate and correction motion vectors
Abstract
The method includes determining at least one candidate motion vector associated with a neighboring block of said current block. A prediction motion vector is determined from the candidate motion vector, and the current block is coded from the prediction motion vector. The prediction motion vector is determined according by determining, for the candidate motion vector, a corrective motion vector so as to minimize a distortion calculated between the neighoboring block successively coded and reconstructed and a prediction block motion compensated by the at least one candidate motion vector modified by the corrective motion vector. The prediction motion vector is then determined from the candidate motion vector modified by the corrective motion vector.
