Digital Signal Processing at Rice University

The Rice Wavelet Toolbox (RWT) is a collection of Matlab M-files and C MEX-files for 1D and 2D wavelet and filter bank design, analysis, and processing. The toolbox provides tools for denoising and interfaces directly with our Matlab code for wavelet domain hidden Markov models and wavelet regularized deconvolution.

NEW Important Note: Earlier version of the Rice Wavelet Toolbox (upto version 2.3) do NOT compile under Matlab versions 6.0 (Release 12) and above. The current version (version 2.4) fixes this compatibilty issue.

Version 1.1 (August 30, 1993) was the first officially released RWT. Version 2.01 (April 18, 1994) had several significant enhancements. The current distribution, Version 2.4 (Dec 1, 2002) below, has been streamlined and packaged for different systems, including Solaris, Linux, and Microsoft Windows. Functions omitted in Version 2.4 can be found in the Version 2.01 distribution.

See the README file for the list of toolbox functions available in Version 2.4.

The Rice Wavelet Toolbox is Open Source Software under this license. It is distributed as-is, free of charge, and without warranty. If you find it useful, please drop us a line at "webmsater-dsp at ece dot rice dot edu".

Version 2.4 Source Code

Source code in gzip compressed format for UNIX users. To unpack gzip'ed files, execute "gunzip rwt.tar.gz" followed by "tar -xvf rwt.tar".
Source code in PC zip compressed format for PC users

The source code contains matlab .m files and .c files that need to be compiled. Please see the installation instructions.

Version 2.4 Pre-compiled Packages for:

Linux version 7.2 compiled using Matlab 6.5 (R13) and Linux Red Hat Release 9.0
Mac OS X version compiled using Matlab 6.5 (R13) and Mac OS X
