PROCESS FOR MATCHING PURSUIT BASED CODING OF VIDEO DATA FOR A SEQUENCE OF IMAGES

摘要

A process involving intra-coding of the current block using spatial prediction based on a matching-tracking algorithm that selects an atom having the highest correlation with the causal neighborhood of the current block from a dictionary of atoms, - determination of a two-dimensional shift between the causal neighborhood and the selected atom, - creation of a new phase adjusted atom taking into account at least the values of the two-dimensional space shift, and - this new atom has a better correlation , In accordance with a matching tracking algorithm, performing steps comprising the use of the new atom for intra prediction. It is applied to video data compression.
