Shape-Adaptive Motion Estimation Algorithm for MPEG-4 Video Coding
This paper presents a gradient based motion estimation algorithm
based on shape-motion prediction, which takes advantage of the
correlation between neighboring Binary Alpha Blocks (BABs),
to match with the Mpeg-4 shape coding case and speed up the
estimation process. The PSNR and computation time achieved by
the proposed algorithm seem to be better than those obtained by
most popular motion estimation techniques.
