摘要：

In all of the video coding standards like H.26X and MPEG-X, much of the compression comes from motion compensated prediction (MCP). Translational motion vectors (MVs) poorly model complex motion and thus coders using polynomial or affine MVs have been proposed in the past. In this paper, we demonstrate a novel affine predictor stage which can be easily incorporated into current codecs greatly increasing MCP quality. If used passively to generate the final prediction, gains of up to 0.7 and 1.6 dB were easily realized for "mobile" and "flower garden" video sequences, respectively. In addition, when the translational MVs are refined, gains of up to 0.98 and 1.88 dB for "mobile" and "flower garden" video sequences were respectively realized.
