基于提升小波变换的快速分形图像编码

摘要

介绍了分形理论和提升小波变换理论,提出提升小波变换结合快速分形编码的混合编码方法。实验结果表明,提出的新算法在解码图像质量略有损失的情况下,图像编码时间和压缩比方面均有良好的效果。%Fractal and wavelet Image compressed has been a hot research topic in recent years.This article firstly introduced fractal theory and the lifting wavelet transformation theory.A hybrid image coding based on lifting wavelet transformation and fast fractal is presented.Satisfactory effect has been obtained while analyzing the result of experiment,especially in the shorting in the encoding time and improving the compression rate.
