- 我们知道，小波变换的一级分解过程是，原始信号分别进行低通、高通滤波，再分别进行二元下抽样，就得到低频、高频（也称为平均、细节）两部分系数；而多级分解则是对上一级分解得到的低频系数再进行小波分解，是一个递归过程。以下是一维小波分解的程序. -We know that a wavelet transform decomposition process is that the original signal were low-pa

- 传统小波阈值去噪法 小波阈值收缩法去噪的主要依据是：小波变换特别是正交小波变换具有很强的去数据相关性，它能够使图像的能量在小波域集中在一些大的小波系数中；而噪声的能量却分布于整个小波域内，因此，经小波分解后，图像的小波系数幅值要大于噪声的系数幅值，可以认为，幅值比较大的小波系数一般以图像信号为主，而幅值比较小的小波系数在很大程度上是噪声。于是采用阈值的办法可以把信号系数保留，而使大部分噪声系数减少至零[-Study on Algor
