摘要

本文提出了一种高效的基于轮廓的编码算法来处理MPEG-4中任意形状的视频对象。该算法基于差分链码的强大功能，差分链码以其简单和高编码效率而闻名。我们通过考虑符号的重复组来改进它，并使用运行长度编码策略来进一步减少编码冗余。实验结果表明，该算法具有良好的编码效率。

An efficient contour-based algorithm for binary video shape coding

In this paper, an efficient contour-based coding algorithm is proposed to handle arbitrarily shape video objects in MPEG-4. The proposed algorithm is based on the powerfulness of differential chain code, which is well-known for its simplicity and high coding efficiency. We improve it by considering the repeating groups of symbols, and use a run length coding strategy to further reduce the coding redundancy. Experimental results show that the proposed algorithm has an excellent coding efficiency.
