Abstract
Official abstract text for this publication.
A method and apparatus are provided for coding a signal from images, the images being split into sub-blocks of pixels. The method includes grouping at least two sub-blocks into at least one block of larger size, when the sub-blocks comply with at least one predetermined grouping criterion. A prediction is performed by applying at least one mode of motion prediction using at least two distinct motion prediction vectors, for at least one block of larger size, the motion prediction vectors being associated respectively with sub-sets of the block of larger size, comprising at least one of the sub-blocks of the block of larger size. The sub-sets are predefined and distinct.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for encoding a signal of images, said images being sub-divided into sub-blocks of pixels, wherein the method comprises: a step of grouping at least three sub-blocks into at least one extended-size block when the sub-blocks meet at least one predetermined grouping criterion; and a prediction step applying at least one motion prediction mode using at least two distinct motion prediction vectors for at least one extended-size block, said motion…
