On level-set type methods for recovering piecewise constant solutions of ill-posed problems
(2009)We propose a regularization method for solving ill-posed problems, under the assumption that the solutions are piecewise constant functions with unknown level sets and unknown level values. A level set framework is established ... -
On multiple level-set regularization methods for inverse problems
(2009)We analyze a multiple level-set method for solving inverse problems with piecewise constant solutions. This method corresponds to an iterated Tikhonov method for a particular Tikhonov functional Gα based on TV–H1 penalization. ...
