摘要： The invention relates to a method for coding a current block comprising an iterative step of decomposition into atoms of a first dictionary of a vector of data comprising at least reconstructed image data associated with pixels situated in a causal neighbouring area of a current block. At each iteration, the step of decomposition into atoms comprises the following steps for: - selecting (32) a first atom in the first dictionary of atoms, - applying (34, 340) a phase correlation between a patch associated with the first atom and a current residue vector, when the first atom is a textured atom, - extracting (34, 342) from the patch at least the part most correlated with the residue vector, the extracted part forming a second atom, - selecting (36) from among the first atom and the second atom, the atom most correlated with the current residue vector, and - updating (38) the residue vector according to the selected atom.

摘要： In interframe video encoding temporal prediction is carried out that is based on motion compensation using a motion vector prediction from a reference frame. But in low bit rate coding, temporal prediction of blocks having texture content achieves only a low Rate-Distortion performance. According to the invention,for blocks having texture content a prediction from a reduced-size texture summary reference picture SRP (i.e. a position referencing) is carried out instead, wherein the components of the prediction vector are derived from the components of vectors for reconstructed blocks adjacent to the current block, and wherein the components of the current block vector refer to the position of the content of the current block within the SRP. The encoded data (SRPI) of the SRP and of the components of the block vectors are transmitted and evaluated at decoder side.
