摘要

全局运动补偿编码是一种基于模型的编码方法

它可以提高编码效率

但是目前由于全局运动补偿编码中的一些关键技术(全局运动估计)的计算量比较大

所以使得全局运动补偿编码还不能在实时应用中得到很好应用.本文就针对全局运动补偿编码中核心技术进行研究

提出快速全局运动补偿编码算法

解决全局运动补偿实时编码问题.通过和MPEG-4中已有的全局运动补偿编码方法实验比较可以看到本文提出的快速全局运动补偿编码方法在保证编码效率的同时编码速度得到了很大提高.

Abstract

Global motion compensation coding is a novel coding method based on models.Its coding efficiency is higher than that of conventional coding method with motion compensation

so it is fit for very low bit-rate applications.But the key technology of global motion compensation coding is not solved well at present

such as global motion estimation

so global motion compensation coding has not been applied widely in real-time applications.This paper focuses some research on key problems of global motion compensation coding to solve real-time global motion compensation coding.The new fast method of global motion estimation is proposed and is used in global motion compensation coding

thus the speed of global motion compensation coding is accelerated.Comparative experimental results are shown in the paper.The speed of global motion compensation coding is improved compared with former method of global motion compensation coding.
