ABSTRACT:
The method comprises the steps for the:calculation of a rate of potential use of an entity of the picture k for a backward predictive coding of the picture k−s, according to the number of vectors of the backward motion vector field of the picture k−s pointing to the entity of the picture k or in its near surroundings and/orcalculation of a rate of potential use of an entity of the picture k for a forward predictive coding of the picture k+p, according to the number of vectors of the forward motion vector field of the picture k+p pointing to the entity of the picture k or in its near surroundings,coding of the picture entity or the picture comprising the entity according to the rate of use of the picture entity.The applications concern the hybrid type compression diagrams.
