提出了一种基于运动特性的自适应快速运动估计算法。该算法充分利用视频图像序列的运动特征进行运动模式判定,实现了一种简单高效的搜索方法,并且根据不同的运动模式动态改变搜索策略。实验表明,新算法在保证重构图像质量的前提下,编码速度有了显著的提高,更适合于实时应用。

In this paper , a novel adaptive motion estimation algorithm based on the character of motion for H.264/AVC coding standard is proposed . This algorithm makes use of the characters of motion, then employs different patterns, so it significantly reduces the search complexity of motion estimation.Experimental results show this algorithm achieves much speedup with negligible PSNR drop and bit-rate increase.
