Regarding Daubechies Wavelet with 22 vanishing points

Started by Huang Andy July 1, 2006
As I studied, p equals the number of vanishing points of Daubeshies Wavelet
in pi, which means p-1 degree order polynomial that can be put in scaling
function. I am trying to find out what those h0, h1, h2...h22 are as I am
trying to program Daubeshies with 22 vanishing points.

Does anyone have any idea what are they? Thank you very much.

Anyone? Yes, Burrus, Gopinath, and Guo do. See, for instance, chapter 5 of _Introduction to Wavelets and Wavelt Transforms_ by them. They have some source code available for their wavelet work here: http://dsp.rice.edu/software Also look into Wavelab: http://www-stat.stanford.edu/~wavelab/ Cheers! --M
