Abstract:
1. A method of compressing a block having a size L×H of a sequence of images, the method comprising using a processor to perform the following steps, in a repetitive manner, on said block: searching, in one of the images of the sequence of images, for the zone of L×H pixels that is the most similar to said block; determining whether the resemblance between said zone and said block responds to predetermined criteria; if said resemblance responds to said criteria, storing a motion vector which indicates the distance between the block and the most similar zone found; if said resemblance does not respond to said criteria, and if the block does not have a predetermined minimum size, cutting said block into sub-blocks and performing a supplemental repetition on each of said sub-blocks, and if said resemblance does not respond to said criteria, and if said block has a predetermined minimum size, storing the block so that while the block is being stored in the course of which the block is compressed without reference to a reference image: wherein said criteria depends on the residue resulting from the prediction.
