Software: MathWorks' Wavelet Toolbox

Announcing The MathWorks' Wavelet Toolbox for use with MATLAB

The MATLAB Wavelet Toolbox, from The MathWorks, provides a
comprehensive collection of M-files and GUI based tools for examining
local, multiscale, and nonstationary phenomena. Wavelet methods offer
additional insight and performance in any application where Fourier
techniques have been used. The toolbox is useful in many signal and
image processing applications, including speech and audio processing,
communications, geophysics, finance, and medicine.

The Wavelet Toolbox is written by Michel Misiti, Yves Misiti, Georges
Oppenheim and Jean-Michel Poggi, of the "Laboratoire de
Mathématiques" Orsay-Paris 11 University, France. Bundled with the
Wavelet Toolbox is the new book, "Wavelets and Filter Banks", by
Gilbert Strang and Truong Nguyen. Many exercises in this book are
drawn from the toolbox.

Features :
- Complete GUI and command line functionality for analysis, synthesis,
de-noising, and compression of signals and images
- Extensive user's guide introduces wavelet concepts and reinforces
them with numerous examples and a complete reference section
- Continuous wavelet transform for multiscale signal analysis
- Analysis and synthesis of 1-D and 2-D discrete wavelet transform (DWT)
- Multiresolution decomposition and analysis of signals and images
- Wide selection of wavelet basis functions (user extensible)
- 1-D and 2-D wavelet packet transforms
- Entropy-based wavelet packet tree pruning for "best-tree" and
"best-level" analysis
- De-noising with soft and hard thresholding
