摘要

本文在H.264编码算法的基础上

提出了改变图像存储结构的1/4像素精度插值

快速搜索位移矢量的四步法

以及快速准确选择预测编码模式等多种新颖的帧间预测快速算法.实验结果表明

与未使用快速算法相比

综合使用本文提出的多种快速算法

在码率增加不到1%

恢复图像平均PSNR(峰值信噪比)下降0.1dB的情况下

编码速度提高13~17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

This paper proposes fast inter prediction methods for real-time video coding based on H.264.These methods include storing structure of 1/4-pel resolution interpolating image

four-step search algorithm for fast block motion estimation and fast decision of inter prediction mode.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.
