FTVd: A Fast Algorithm for Total Variation based Deconvolution

FTVd refers to Fast Total Variation (TV) deconvolution, and is a TV based deconvolution / denoising package. The latest package includes fast solvers for the TV/L2 and TV/L1 models, which are compatible with both grayscale and color images.
FTVd can be easily modified to work with three and higher dimensional image/data.
