Paper Abstract

Wyner-Ziv video coding has gained considerable interests in the research community. In this paper, we examine the Wyner-Ziv video coding performance and compare it with conventional motion-compensated prediction (MCP) based video coding. Theoretical and simulation results show that although Wyner-Ziv video coding can achieve as much as 6dB gain over conventional video coding without motion search, it still falls 6dB or more behind current best MCP-based INTER-frame video coding. We further investigate the use of sub-pixel and multi-reference motion search methods to improve Wyner-Ziv video coding efficiency.
