摘要

本文提出了一种简单而有效的方法来减少双向块匹配运动估计的计算量。与现有的公式不同，我们重用了p帧获得的运动矢量，从而省去了双向预测b帧的不必要的运动矢量计算。实验结果表明，这种增强将双向运动估计的复杂度降低了1/3，且对主观图像质量没有明显影响。

An algorithmic enhancement for reducing computations of bidirectional motion estimation

This paper presents a simple yet efficient technique to reduce computations of bidirectional block-matching motion estimation. Unlike existing formulations, we reuse motion vectors obtained for P-frame to omit unnecessary motion vector calculations for bi directionally predicted B-frame. Experimental results show that such an enhancement lowers complexity of bidirectional motion estimation as much as 1/3 without visible impact on subjective picture quality.
