摘要

H.264采用了多参考帧技术

大大提高了预测精度

改善了视频图像质量

然而这种特性同时也带来了很高的计算复杂度.为了降低H.264编码器的计算复杂度

本文提出了一种多参考帧快速选择算法.该算法充分考虑多参考帧中运动矢量的相关性以及中心偏置特性

通过对待选参考帧进行预选择

有效减少了需要进行全搜索的参考帧个数

提高了编码速度.实验结果表明

该算法在保持图像质量和码率变化很小的前提下

运动估计模块编码速度提高了30.91%.

Abstract

The multi-reference frames technique is employed in H.264

which can improve prediction precision and meliorate video pictures quality greatly.However

the feature calls for higher computational complexity simultaneity.In order to reduce the complexity of H.264 encoder

a fast multi-reference frames selection algorithm is presented in this paper.By considering the correlation and center-biased characteristic of motion vectors in multi-reference frames adequately

the proposed algorithm makes selection for multiple references in advance

thereby it can effectively decrease the numbers of reference frames making full search and improve the coding efficiency.Experimental results show that the proposed methods can improve the speed of motion estimation module by 32.14% on average with less performance degradation and bit-rate increase.
