适应于极低传输码率的物体基图像编码

Object-Oriented Image COding at Very Low Bitrates

本文介绍了物体基编码的基本方法、算法流程及其关键技术。该编码方法的重要特点是既考虑到所处理对象的一般性，又利用了一定的先验知识，因此可用于极低传输速率的图像编码（６４ｋｂｉｔ／ｓ以下），是电视电话中的一种很有应用前景的编码方法。

This paper describes the basic concept of object-oriented image coding,as well as some of its keytechniques. Since it is based on a common source model,and also taking the prior-knowledge of objects to becoded into account.It can be used in low bitrates image coding,esspecially in videophone application.
