Abstract
The process of compression of a block of a size L.times.H of a sequence of images comprises, in a repetitive manner, for said block: a search step, in one of the images of the sequence of images, for the zone L.times.H pixels the most similar to said block; a step of determining whether the resemblance between said zone and said block responds to predetermined criteria; if said resemblance responds to said criteria, a step of storing the 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, a step of cutting out said block into sub-blocks and a supplemental repetition, for each of said sub-blocks, and if said resemblance does not respond to said criteria, and if the block has a predetermined minimum size, a step of storing the block in the course of which the block is compressed without reference to a reference image.
