Convex optimizationMatlab code to compute the proximity operator or project on the ball of several norms: l_1, l_2, l_inf, l_1,2, l_inf,2, l_1,inf... : Condat_proxs.m C code to project a vector onto the simplex (by sorting, using a heap, algo. of Michelot, algo. of Duchi et al...): condat_simplexproj.c. This file also includes an efficient C implementation of Floyd and Rivest's SELECT algorithm (e.g. to find the median of a vector). Matlab code to project a matrix onto a l1,infinity norm ball: projl1inf.m. Much faster than A. Quattoni's code on her webpage.
Matlab code for total variation denoising: TVdenoise.m
parrotgray.png C code to perform 1D total variation denoising or fused lasso signal approximation (with my algorithm of 2013 or the taut string algorithm): condat_fast_tv.c.
For use in Matlab, mex files made by
Stephen Becker.
SuperresolutionMatlab code to recover the locations and amplitudes of spikes, from noisy lowpass samples (several methods implemented: matrix pencil, Cadzow denoising...): pulses_recovery.m Color image processing for digital photographyMatlab code to perform demosaicking or joint demosaicking/denoising by total variation minimization: denoisaicking_TV_Condat.zip and by Tikhonov regularization: denoisaicking_Condat.zip Matlab code to generate random red, green, blue patterns (color filter arrays) with blue noise properties: CFArandom1.m, CFArandom2.m
