The program tvd.c is a C program by Laurent Condat for fast exact TV denoising. The algorithm is described in ‘A direct algorithm for 1D total variation denoising’, L. Condat, IEEE Signal Proc. Letters, 20(11):1054-1057, 2013. To compile this program to use it in MATLAB, type 'mex tvd.c' at the MATLAB command line.
