说明:  此为基于二代提升小波的阈值压缩算法源码,其中可以设置小波变换的分解层数,使用的小波名称,及各层阈值设置计算公式中的参数。并将低频系数转化为十六进制,方便在其上进一步压缩,如采用Huffman压缩等,程序思路清楚,附有完整的注释,可以使用多种小波,并且很好得体现了二代小波的思想,对于初学小波者帮助很大。
(based on the second generation of this upgrade wavelet compression algorithm threshold source, which can set wavelet transform decomposition level, the use of wavelet name, threshold levels and set the formula for calculating the parameters. And low-frequency coefficients into hexadecimal facilitate its further compression, such as the Huffman compression. procedures ideas clearly, with the integrity of the Notes, you can use a variety of wavelet, and reflected very well in the second generation wavelet thinking, For beginners who wavelet of great help.)
