Walsh
- Walsh变换 (FWT)算法设计中的外部和内部调序问题 ,对四种不同的序分别进行分析 .从算法流程图和序码分析两个方面进行外部调序 ,用码位倒置和对偶演化相结合进行内部调序
FastWalshTransform
- fwt,fwt2分别是一维、二维快速沃尔什变换函数,采用蝶形快速算法编写，要比利用矩阵相乘得到变换结果的离散沃尔什变换快很多-fwt, fwt2 are one-dimensional, two-dimensional fast Walsh transform function, the use of butterfly Fast Algorithm for the preparation of, than the use of transformation matrices to be the
fwt2d_demo
- 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
MATLAB2-D(FWT)wavelet
- 经典的二维小波变换的例子，可以低通，高通滤波和取低频或高频灰度等，非常有价值！-The classic example of two-dimensional wavelet transform, can be low pass, high pass filter and take low-or high-frequency gray, etc., is very valuable!
waveback
- 多层次二位图像 快速小波变换 实例 自己手写- WAVEBACK Performs a multi-level two-dimensional inverse FWT.
FWT
- 根据个人对小波的理解，用卷积进行小波分解的一个简单小程序，有助于理解。-Based on personal understanding of Wavelet , I write a simple little program by myself that use convolution to do a wavelet decomposition，it can help to understand.
