影响分形编码算法性能因素的分析

Analysis on the factors influencing the fractal image coding algorithm performance

为提高分形图像压缩的速度,本文分析研究了用邻域匹配的四叉树分形编码方法,提出了一种基于区域分割和十字搜索模型的分形图像压缩的编码方法。实践证明,这种方法编码速度快,压缩效果好。

In order to achieve a good velocity for fractal image compression ,this paper analyzes and studies a quadtree arithmetic fractal image coding and suggests a reglon-based transformation that extends the block-based scheme. This method can achieve a higher velocity of the coding because of less searching and can procure a good compression effect.
