运动估值是视频压缩编码的核心E针对块匹配算法中广泛采用的MAD准则的不足,提出了一种约束条件帧间差值运动估值匹配准则,通过理论分析和实验比较,证实了新匹配准则的优越性.

Motion estimation and motion compensation(ME/MC)is the core technology oI motion picture coding. A new motion estimation scheme based on a novel matching criterion.Restrictive Conditional Interframe Difference(RCID).is proposed in this paper. The new matching criterion overcomes the shortages of MAID criterion and has the equivalent computing complexity with MAD. The theory analysis and experimental results show the ellectiveness and superiority of RCID criterion.
