摘要
根据小波及分形理论的特性提出了一种小波域分形图象数据压缩方法,基本思路是利用小波变换实现图象的多分辨率分解,采用分形理论对具有相似性的小波分解图象进行编码,从而充分利用了两种理论的优点,提高了图象压缩系统的压缩率和容错率,最终提高重构图象的质量。
Based on the characteristic of wavelet and fractal, a scheme for image data compression is presented. In this method, we bring forward a new way to get the code by using fractal. Experiment results show that this method will achieve high quality reconstructed image in very low bit rate.
