The tvreg package applies total variation (TV) regularization to perform 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 Min TV(u) + d-?Tz d?T¬ F(K*u,f) dx, uto perform denoising, deconvolution, and inpainting as special cases. It is efficiently solved using the split Bregman method. Also included is an 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.=== Get Started Quickly in MATLAB ===Compiling is not required to use tvreg in MATLAB. Try the demos tvdenoise_demo Total variation denoising demo tvdeconv_demo Total variation deconvolution demo tvinpaint_demo Total variation inpainting demo chanvese_demo Chan-Vese segmentation demoFor improved performance, run the included script "complex_mex.m" to compile the main computation routines as MEX functions. This requires that FFTW is installed, please see section 7.3 of the documentation.=== Get Started Quickly in C/C++ ===1. Install the FFTW library ( Windows users can download precompiled DLL files from Compile the programs with GCC using "make -f makefile.gcc" or Microsoft Visual C++ using "nmake -f". See section 7 of the documentation for help.3.
