This paper presents a novel fast motion estimation (ME) algorithm for shape coding in MPEG-4, which takes full advantage of the correlation between adjacent binary alpha blocks (BABs) and the match characteristics of boundary BABs.

• 提出了一种新的形状快速运动估计算法,用于加快MPEG 4视频对象的形状编码过程。 该算法充分利用了邻近形状块的运动向量之间的相关性、边界形状块的匹配特性。
