METHOD AND DEVICE FOR ENCODING AN IMAGE SEQUENCE USING TEMPORAL PREDICTION, SIGNAL, DATA MEDIUM, DECODING METHOD AND DEVICE, AND CORRESPONDING COMPUTER PROGRAM PRODUCT

摘要

The invention relates to a method for coding an image sequence, comprising a step of coding at least one block of a current image of the sequence, implementing a prediction (11) associating the block with at least one a corresponding block in a reference image. According to the invention, the prediction (11) comprises the following steps, for at least one given block of the current image or of the reference image: - determination (111) of a plurality of control vectors for the block ; at least one division (112) of the block into sub-blocks; determining (113) a plurality of control vectors for the sub-blocks; determining (114) a prediction value for at least one point of the current image. In addition, the method comprises a step of inserting, in a signal representative of the sequence, information of reconstruction of the control vectors for the given block.
