The tvreg package performs total variation (TV) regularized image denoising, deconvolution, and inpainting. Three different noise models are supported: Gaussian (L2), Laplace (L1), and Poisson. The implementation solves the general TV restoration problem
to perform denoising, deconvolution, and inpainting as special cases. It is efficiently solved using the recent split Bregman method. Also included is an efficient implementation of Chan-Vese two-phase segmentation. All functions support grayscale, color, and arbitrary multichannel images.
Please see the included documentation file tvreg.pdf for details.
Compiling is not required to use tvreg in MATLAB. Try the demos
For improved performance, run the included script complex_mex.m to compile the main computation routines as MEX functions. This requires that FFTW3 is installed, please see section 7.3 of the documentation.
