发明名称 METHODS AND DEVICES FOR ENCODING AND DECODING AN IMAGE SEQUENCE IMPLEMENTING A PREDICTION BY FORWARD MOTION COMPENSATION, CORRESPONDING STREAM AND COMPUTER PROGRAM
摘要 A method and apparatus for encoding a sequence of images by predicting at least one current image by forward motion compensation from at least one reference image. Prediction implements, for at least one current block of the current image: forward projection of a block of the reference image on the current image, delivering a projected block at least partially overlapping the current block; partitioning the current block delivering a sub-block at least partially overlapped by at least one projected block; and at least one iteration of the following steps for at least one overlapped sub-block: checking that the overlapped sub-block complies with a predetermined allotting criterion; with a positive check, allotting, to the overlapped sub-block, one of the projected motion vectors; and with a negative check, and so long as a predetermined minimum size is not reached for the overlapped sub-block: partitioning of the overlapped sub-block.
