摘要

本文对H.264速率控制的空间复杂度预测进行了分析。提出了一种基于宏块的编码模型，利用了宏块复杂度的空间相关性，提高了编码效率。将该算法与JVT-G012速率控制算法进行了比较，结果表明，该算法可将预测误差提高17%，视频质量提高0.17dB。

Spatial complexity prediction for H.264 rate control

This contribution presents an analysis of spatial complexity prediction for H.264 rate control. A macroblock based model is proposed showing that we can take profit of the spatial correlation of macroblocks complexity and offering an improvement in coding efficiency. We compare our algorithm to JVT-G012 rate control algorithm and demonstrate that we can improve the prediction error by17 % and the video quality by 0.17dB.
