中文摘要：

针对HEVC中PU划分模式和帧间运动模式的选择引起的高复杂度，提出一种快速帧间预测算法。首先，判断图像的运动状态和纹理复杂度，根据当前图像的时空域相关性及图像内容的特点，减少PU划分模式。然后，根据运动剧烈程度对当前PU运动模式预判，从而不需要遍历所有的运动模式。实验结果表明，在视频重建质量基本相当的前提下，改进后的算法编码时间与参考算法相比节省30％～60％左右。

英文摘要：

In order to solve the high complexity which result from the choice of PU mode and frame movement patterns which is the new technology in HEVC, a fast inter frame Prediction algorithm is proposed in this paper. Firstly, it is determine the movement of images and texture complexity, and reduce PU mode based on the current image in spatial domain correlation and characteristics of image content. Then, according to the characteristics of inter-frame motion mode,it is predict the current PU Motion mode by mo- tion state, and it is not need traverse all of the patterns of motion. Experimental results show that the modified algorithm saves enco- ding time 30% - 60% and video quality loss is negligible.
