METHODS AND APPARATUS FOR CODING OF MOTION VECTORS
摘要
A method and apparatus is described for coding motion information in video processing of a stream of image frames and for avoiding the drift problem. The method or apparatus is for providing motion vectors of at least one image frame, and for coding the motion vectors to generate a quality-scalable representation of the motion vectors. The quality-scalable representation of motion vectors and a set of one or more enhancement-layers of motion vectors. The method of decoding and a decoder for such coded motion vectors as part of receiving and processing a bit stream at a receiver includes the base-layer of motion vectors being losslessly decoded, while the one or more enhancement layers of motion vectors are progressively received and decoded, optionally including progressive refinement of the motion vectors, eventually up to their lossless reconstruction.
