摘要

H.265的计算复杂度非常高，因为它使用了大量的块大小来进行运动估计(ME)。为了减少它，在H.265参考软件中推荐使用方形图案和菱形图案。本文提出了一种新的非对称菱形搜索模式，进一步减少了模型的计算量。与推荐的方形搜索模式相比，新模式将ME的计算负荷分别降低了近69.5%和72%。同样，编码时间减少了65%和69%。比特率和PSNR几乎没有变化。

Asymmetric diamond search pattern for motion estimation in HEVC

The computational complexity of H.265 is extremely high since it uses a lot of block size for motion estimation (ME). In order to reduce it, square pattern and diamond pattern are recommended in the H.265 reference software. In this paper, the new asymmetric diamond search patterns are proposed to reduce even further the calculation load of the ME. The new patterns reduce the computation load of ME an impressive amount of nearly 69.5% and 72%, respectively, comparing to the recommended search pattern of square pattern. Similar, the encoding time reduces 65% and 69%. The bit rate and PSNR are virtually unchanged.
