VC++实现的二维小波变换源代码，已经测试，可用。用于图像去噪、压缩等 -VC 2D wavelet transform source code has been tested and available. For Image Denoising, compression

小波变换源码，国外VC开发的，效果比较好 I ve been involved with wavelet-analysis since my Ph.D studies and over the years developed various wavelet-transforms C++ libraries. This one concerns 2D implementation of the Fast wavelet transform (FWT). The 2D FWT is used i
