Several python libraries implement discrete wavelet transforms. However, none of them, or at least none that I know, is aimed at scientific use. This library aims at filling this gap, in particular considering discrete wavelet transform as described by Percival and Walden. This module started as translation of the wmtsa Matlab toolbox (http://www.atmos.washington.edu/~wmtsa/), so most naming conventions and most of the code structure follows their choices.

libdwt is a cross-platform discrete wavelet transform library implemented in C language. The library implements fast wavelet transform algorithm using lifting scheme. Cohen-Daubechies-Feauveau wavelets with 4 vanishing moments were used.

It is often necessary to smooth high frequency fluctuations out of data streams sequenced by time, position, etc. The 'smooth' utility applies such smoothing using the wavelet algorithm. This implementation of wavelet smoothing was optimized for use in a data stream. It was adapted from HMMSeg Wavelet.Java by Thomas E. Wilson, University of Michigan. HMMSeg Wavelet.Java was written by Andrew Hemmaplardh, University of Washington. http://noble.gs.washington.edu/proj/hmmseg/ Unsupervised segmentation of continuous genomic data, Bioinformatics 2007 23:1424-1426 See the above references for a more thorough description of the principles behind wavelet smoothing.

blitzwave is a c++ wavelet library building on the blitz++ array classes. NOTE: blitzwave has moved to GitHub - the new project URL is http://github.com/oschulz/blitzwave/ .

Adaptive Wavelet Applications on general domains - the goal still far away. But the first step is done. This project aims at introducing wavelet methods realized in C++. As building block it uses FLENS.

Scilab Wavelet Toolbox, is designed to emulate Matlab Wavelet Toolbox. Combined with Scilab Image processing toolbox on sourceforge, one could do image wavelet processing the way as the Matlab user does.

Continuous wavelet transform library

wxMorlet implements the new algorithm (see "Documentation") for the computation of the continuous wavelet transform with the Morlet wavelet. wxMorlet calculates it as a numerical solution of the proper PDE and represents the results in a graphical form
