1. A process for the coding of video data of a sequence of images comprising splitting of an image into blocks, intra coding of a current block using spatial prediction based on a matching pursuit algorithm, selecting, from a dictionary of atoms whose theoric expressions are known, the atom the most correlated with a causal neighborhood of the current block, further comprising: determination of a two dimensional spatial shift between the causal neighborhood and the selected atom, wherein the two dimensional spatial shift is reflected as a phase change in the Fourier Domain; generation of, at least, a new phased atom taking into account the values of the two dimensional spatial shift, use of this new phased atom for intra prediction, according to the matching pursuit algorithm, if better correlated than the selected one.
