Primal-dual methods in total variation regularized L1 and L2 functionals arising in image denoising
Forthedenoising of block images using the nonsmooth L2 TV-model, a new method based on the algorithm introduced by Chambolle [8] and on the primal-dual active set strategy due to Hinterm¨uller and Stadler [28] is introduced. The active set technique aims at decomposing the image into edges (active s...
