基于小波变换的图像压缩编码方法的比较及实现

The Comparison and Implement of Wavelet-transform-based Image Coding Algorithm

对基于小波变换的嵌入式图像编码方法中最具代表性的EZW和SPIHT编码算法的原理进行了分析比较、并予以实现。

The EZW and the SPIHT are the representative methods of the wavelet-tramsforsform-based embedded wavelet image coding algorithms. This paper analyses the principle and implements these coding algorithms, and introduces the wavelet-transform-based embedded wavelet image coding methods.
