Abstract

A novel lossless coding scheme for video signals is described. The scheme uses a block-adaptive 3D prediction method that predicts a video signal based on both the current and motion-compensated previous frames. The resulting prediction errors are encoded by using a kind of context-adaptive arithmetic coder, Several coding parameters such as prediction coefficients and motion vectors are iteratively optimized for each frame so that the overall coding rate can be a minimum. Moreover, a quadtree-based variable block-size motion compensation technique is introduced for efficient representation of motion information. Experimental results show that the coding rates of our scheme axe 11-17% lower than those of the H.264-based lossless coding scheme.
