摘要
分形图像压缩编码方法以其高压缩比的潜在性能而在近年来倍受重视,但是分形方法还存在着一些问题亟待解决。本文所提出的基于小波变换的分形压缩方法不仅弥补了分形方法编码时间过长的缺点,而且还使分形方法高压缩比的优点,得以进一步发挥。
Fractal compression is an attractive compression method with the ability of high compression ratio(CR).But there are some problems that have not been well solved yet.The wavelet based fractal compression method proposed in this paper can not only make up its weakness,such as long encoding time,but also further bring out its merits,such as high compression ratio.
