Abstract: The motion estimation research based on the H.264/AVC standard，which is a research hotspot in video compression field.A fast motion estimation algorithm based on adaptive threshold static block detection is proposed in this paper.It uses the statistics of graph sequence to early terminate the search，proposes a synthetic diamond-rood-cross search pattern，using different strategy according to the video sequence.Compared to the conventional fast search algorithm，experiments show that with the same image quality assurance，the speed is 10 times up.

摘要： 基于H.264/AVC标准的运动估计研究一直是视频压缩研究的重点，提出一种自适应阀值静止块检测的运动估计算法。根据图像序列的统计特性提前中止搜索，提出菱形-小交叉-十字综合搜索算法，对不同的视频序列采取不同的搜索策略。与常规快速搜索算法相比较，实验结果表明，搜索速度提高了10倍，图像质量也得到了保证。
