摘要
提出了一种基于H.264的快速帧间预测模式选择算法,该算法针对H.264中帧间预测模式采用的对所有候选模式进行全搜索的方法,提出了一种基于图像运动剧烈程度分级的模式选择算法,达到快速选择预测模式的效果。实验证明,本文提出的模式选择算法与H.264原算法相比在基本保持原算法率失真特性良好的同时较大幅度的提高了编码效率。
This paper presents a fast,inter-frame prediction mode selection algorithm based on H.264.For H.264.The algorithm method of inter prediction mode searches for all the candidate models.This paper proposes an algorithm based on an image intensity classification model selection system to quickly select the best prediction model.Experiments show that the algorithm proposed in this paper increases coding efficiency under the premise of maintaining the basic rate-distortion characteristics.
