Software

SGWT toolbox on epfl wiki

MATLAB toolbox implementing the Spectral Graph Wavelet Transform for defining wavelet transforms on arbitrary weighted graph domains, as described in (Hammond et al, 2009) . This includes both the direct implementation in spectral domain, and the fast algorithms based on Chebychev polynomial approximation.

BPDQ toolbox on epfl wiki

MATLAB toolbox implementing the Basis Pursuit De-Quantization algorithm for recovery of sparse signals from quantized compressed sensing-type measurements. This toolbox includes demos recreating the numerical experiments from (Jacques et al, 2009).

OAGSM / NC Toolbox [ .tar ]   [ .zip ]

MATLAB code for implementing the OAGSM / NC (Oriented Gaussian Scale Mixture with Non-Oriented Component) Algorithm for Image Denoising, described in (Hammond and Simoncelli, 2008)

This code relies on the MATLAB Steerable Pyramid toolbox, available from the lcv website.
