摘要： 运动估计是AVS视频编码的重要环节，提高运动估计的速度和精度有利于实现高质量实时编码器。针对几种AVS运动估计搜索过程不能很好地兼顾速度和精度，引入了自适应搜索选择的算法。通过不同视频序列实验表明，该搜索方案较好克服了现有算法不足，对运动剧烈程度不同的视频序列具有较好的编码速度和适应性。

Abstract： Motion estimation is an important part of AVS video coding, improve the speed and precision of motion estimation is conducive to the realization of high quality real-time code encoder. In view of the AVS motion estimation can't several traditional search model using a good balance between speed and accuracy of search algorithm is introduced for adaptive selection. Through the AVS encoder different video sequence experiments show that, the search scheme overcomes the shortcomings of traditional search model, the severe degree of different video sequences of movement has better coding speed and adaptability.
