Abstract:
1. A method for encoding a sequence of images, comprising: implementing a prediction of least one block of a current image of the sequence from a block of a reference image pre-divided into blocks, said prediction associating at least one block of a current image of said sequence with at least one corresponding block in at least one intermediate image time-localized between said reference image and said current image, to be forward motion-compensated, said intermediate image or images having been previously encoded, a phase of optimized partitioning delivering a common partitioning of at least one given block of said reference image, comprising the following steps: a phase of predicting said current image from said intermediate image obtained preliminarily from said reference image to which said common partitioning into basic sub-blocks for said given block has been applied, said prediction phase comprising the following steps: forward motion-compensating said sub-block of said intermediate image towards a corresponding sub-block of said current image by means of said first set of modified control vectors.
