摘要
综合利用了位图压缩、小波分解、分形迭代与霍夫曼编码技术，提出了一种图像压缩的新方法．该方法采用位图平面分解进行第一步压缩，然后对位图压缩后的图像进行正交小波分解，利用相同尺度和不同尺度上的局部相似性构造迭代函数系统，最后对所有参数进行霍夫曼编码．
A new adaptive image compression method is presented. Firstly, an image is decomposed by bits plane and is compressed. Secondly, the image compressed by bits compression is decomposed by wavelet transformation. Using the image decomposed similarity at same scale or different scale, iterated function system is constructed. Finally, all parameters are encoded by Huffman method. The experiment results demonstrate that the method is efficient.
