METHOD FOR CODING AND FOR RECONSTRUCTION OF A BLOCK OF AN IMAGE SEQUENCE

摘要

The invention relates to a method for coding a current block comprising the following steps for: - determining (30, 32, 34) a prediction block from the current block, - determining (36) a residue block by extracting from the current block the prediction block, - coding (38) the residue block, the method being characterized in that the prediction block from the current block is determined according to the following steps for: - determining (30) an initial prediction block from motion data and at least one reference image previously coded and reconstructed, - applying (32) an atomic decomposition method on a vector of data Yep, comprising the image data of neighbouring blocks of the current block previously coded and reconstructed and the data of the initial prediction block, and - extracting (34) from the decomposed vector the data corresponding to the current block, the extracted data forming the prediction block.
