基于图像活动性的序列图像分形编码方法

介绍了分形的概念以及分形压缩的主要思想；阐述了传统的分形图像压缩编码的基本原理与实现方法；提出了一种基于图像活动性序列图像分形编码方法。该方法首先由相邻帧之间的预测差值来判断当前编码块的活动性，然后根据图像的活动性，对不同特性的块采用不同的分形编码策略，最后对编码后得到的迭代函数系统（IFS）码进行可变长度编码（VLC），以获得更高的压缩比。

A Method of Sequence Image CodingBased on the Activity of Image

The concept of fractal and the idea of fractal compressare introduced in this paper. The basic principle and implementing method of the tradition fractal image compress are expounded. A method of sequence image coding based on the activity of image is proposed . In this coding algorithm, the activity of the current block is judged by the predict error of this block at first, then for every block with different activity , different fractal coding strategy is adopted. In order to gain higher compress ratio, VLC(Variable length code) is used to the IFS (Iteration Function System) code.
