The DWT is basically repeated application of convolution with a scaling or wavelet filter followed by decimation (downsampling) by two. Here is a filterbank diagram from wikipedia illustrating this: After a certain number of levels, the discrete signal has been decimated as far as possible (i....

不同的小波基函数,是由同一个基本小波函数经缩放和平移生成的。 小波变换是将原始图像与小波基函数以及尺度函数进行内积运算,所以一个尺度函数和一个小波基函数就可以确定一个小波变换 小波变换后低频分量 基本的小波变换函数 二维离散小波变换: (官网上的例子) ...
