Patent ID: 8755618

Claim:
A method for coding a current block of a sequence of images comprising the following steps of: decomposing iteratively, into atoms of a first dictionary, a vector of data comprising at least reconstructed image data associated with pixels located in a causal neighbourhood of said current block, said first dictionary comprising analytical atoms and textured atoms, and extracting from said decomposed vector data corresponding to said current block, said extracted data forming a prediction block, determining a residue block by extracting from said current block said prediction block, coding said residue block, wherein, at each iteration, said step of decomposition into atoms comprises the following steps of: selecting a first atom in said first dictionary of atoms, applying a phase correlation between a patch and a current residue vector when said first atom is a textured atom, wherein said patch is associated with said first atom and is bigger than said first atom, extracting from said patch at least the part most correlated with said residue vector, said extracted part forming a second atom of same size as said first atom, selecting from among said first atom and said second atom, the atom most correlated with said current residue vector, and updating said residue vector according to said selected atom.
