Brendt Wohlberg and Paul Rodríguez, "An Iteratively Reweighted Norm Algorithm for Minimization of Total Variation Functionals", IEEE Signal Processing Letters, vol. 14, no. 12, doi:10.1109/LSP.2007.906221, pp. 948--951, Dec 2007

Abstract

Total Variation (TV) regularization has become a popular method for a wide variety of image restoration problems, including denoising and deconvolution. A number of authors have recently noted the advantages of replacing the standard l2 data fidelity term with an l1 norm. We propose a simple but very flexible method for solving a generalized TV functional which includes both the l2-TV and and l1-TV problems as special cases. This method offers competitive computational performance for l2-TV, and is comparable to or faster than any other l1-TV algorithms of which we are aware.
