METHOD AND DEVICE FOR ENCODING A SEQUENCE OF IMAGES IMPLEMENTING A TEMPORAL PREDICTION, CORRESPONDING SIGNAL, DATA STORAGE MEDIUM, METHOD AND DECODING DEVICE AND COMPUTER PROGRAM PRODUCTS
A method and apparatus are provided for coding a sequence of images. The method includes a step of coding at least one block of a current image of the sequence, implementing a prediction associating the block with at least one corresponding block in a reference image. The prediction includes the following steps, for at least one given block of the current image or of the reference image: determination of a plurality of control vectors for the block; at least one splitting of the block into sub-blocks; determination of a plurality of control vectors for the sub-blocks; and determination of a prediction value for at least one point of the current image. Moreover, the method includes a step of inserting, into a signal representative of the sequence, information regarding reconstruction of the control vectors for the given block.
