摘要

根据H.264预测帧的编码算法

本文研究了利用图像序列的时/空相关性

正确选择预测编码模式的快速算法

并提出了模式选择参数的自适应更新算法.实验结果表明

与未使用快速模式选择算法相比

在码率增加2%

恢复图像平均PSNR(峰值信噪比)下降不到0.2dB的情况下

使用快速算法的编码速度提高2~3倍

满足实时视频通信的要求.算法与H.264标准兼容

可用于实际产品.

Abstract

Based on H.264

this paper proposes a novel fast selecting inter prediction mode algorithm by using temporal/spatial correlation of video sequence.Two key parameters by which inter prediction mode is determined is adaptive updated.Simulation results show that inter macroblock encoding is obviously speeded up by using above methods.Furthermore

these algorithms are compatible with H.264 standard

and can be used in practice.
