小波分析应用于迭代分形和统计预测分形相结合的图像编码方法

Application of Wavelet Analysis to a Combination of Iterative Fractal Coding and Statistic Prediction Fractal Coding Techniques

本文讨论并实现了一种基于小波分析的迭代分形和统计预测分形相结合的图像编码压缩方案，对于典型的512×512×8的灰度图像达到了比特率为0．236bpp，峰值信噪比约30．

Based on wavelet analysis,an approach combining iterative fractal coding and statistical prediction fractal ceding to image compression is presented. Experiment shows that bit rate=0. 236 bPP and SNR=30. 18db are achievable for the typical 512 × 512 × 8 gray image.
