H.264预测编码关键技术的研究分析
Research on inter prediction coding for H.264 video coding
【摘要】 H.264是目前最新的视频编码标准,相对于以前的ITU-T视频编码标准和mpeg序列标准具有更高的压缩效率.编码效率的提高主要归根于精确的帧间预测编码,其中包括多种块模式,多参考帧运动估计和分数像素精度3种新技术的采用.对这些帧间预测编码技术进行研究和分析,主要是分析这些技术与H.264基本配置之间的比较.
【Abstract】 The JVT/H.264 is the new video coding standard which offers significantly better video compression efficiency than previous ITU-T standards and MPEG standards.The improvement in the rate-distortion performance in H.264 is mainly due to accurate inter prediction coding with different mode decisions including multiple block size,multiple reference frame motion estimation and fine sub-pixel motion vectors.In this paper,there are analyses and regulations of the inter prediction coding,and some comparisons with the base profiles in H.264 were also provided.
【Key words】 H.264; video coding; prediction coding; motion estimation;
