FTVd: A Fast Algorithm for Total Variation based Deconvolution

FTVd refers to Fast Total Variation (TV) deconvolution, and is a TV based deconvolution package. FTVd version 1.0 was released on Oct. 9, 2007. FTVd version 2.0, released on August 1, 2008, is a major upgrade to version 1.0. Compared with v1.0, this version has improved parameter selections in continuation and stopping criterion. More importantly, FTVd_v2.0 has a much expaned capability including color image restoration and impulsive noise elimination.
