Nusc

It is well-known that for images, symmetric wavelets have some advantages, does anyone know what they are and why? And is CDF 97 a symmetric filter?

The one-dimensional Haar transform is contructed by taking two numbers, a and b and mapping them to a lowpass value sqrt(2)*a/2 + sqrt(2)*b/2 and a highpass value sqrt(2)*b/2 -sqrt(2)*a/2. For...

Hey guys I'm trying to denoise some images using the following script. It was originally in Mathematica 5.2 and I'm trying to convert it to Mathematica 7.0 but so far...
