基于分形的图像分层编码方法

An Image Hierarchical Encoding Scheme Based on Fractal

提出将基于对称短核滤波器（ＳＳＫＦ）的子带编码和基于迭代函数系统（ＩＦＳ）的分形图像编码相结合的图像编码方法．实验结果表明，与基本的自动分形图像编码方法相比，信噪比提高而运算时间和码率均下降．

Presents an image encoding method combining sub band dividing based on symmetry short kernel filters(SSKF) and fractal encoding based on iterated function system(IFS) Compared to basic automatic fractal coding method, computation time and code rate is saved with improved quality of the reconstructed image.
