快速分形图象编码

Fast Fractal Image Coding

提出了一种新的快速分形图象编码方法。该方法通过自适应的图象分块、相似块集的矩分类、相似块和图象块的正交分解以及象素递增的动态搜索等４ 个步骤来加快分形图象编码的过程。实验结果表明，提出的方法在缩短编码时间方面确有其效，特别是对于细节丰富的图象，效果尤为明显。

This paper presents a new method for fast fractal image coding. This method speeds up the coding process by adaptive partition of image, moment classification of domain pool, orthogonal decomposition of domain blocks and range blocks, as well as dynamic search by pixel after pixel. The experimental results show that the method presented in this paper performs well in speeding up the coding process, especially for those images that have much more details in them.
