Abstract:
A method for coding a current block is disclosed. The method comprises: determining a prediction block from the current block, determining a residue block by extracting from the current block the prediction block, and coding the residue block. The prediction block from the current block is determined according to the following steps for: determining an initial prediction block from motion data and at least one reference image previously coded and reconstructed, applying an atomic decomposition method on a vector of data Ycp, 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 from the decomposed vector the data corresponding to the current block, the extracted data forming the prediction block.
