摘　　要：利用低码流、运动量较小的视频序列前后帧具有很强的时空相关性的特点，进行了算法改进的实验，在保持视频性能的同时，减少了运动搜索的计算量，提高了运动估计的速度。In this paper,an adaptive motion search algorithm is presented to reduce the computational complexity by exploiting the spatial-temporal correlation in video sequences.Several experimental results demonstrate the algorithm's superiority in situations for low-bit video sequences,such as video-phone,video-conference and video monitor applications.

关 键 词：运动估计 自适应运动搜索 宏块类型 低码流视频
