A data-driven iteratively regularized Landweber iteration
Andrea Aspri, Sebastian Banert, Ozan Öktem +1
We derive and analyse a new variant of the iteratively regularized Landweber iteration, for solving linear and nonlinear ill-posed inverse problems. The method takes into account t…
Invariant -minimal sets and total variation denoising on graphs
Clemens Kirisits, Otmar Scherzer, Eric Setterqvist
Total variation flow, total variation regularization and the taut string algorithm are known to be equivalent filters for one-dimensional discrete signals. In addition, the filtere…
Regularization with Metric Double Integrals of Functions with Values in a Set of Vectors
René Ciak, Melanie Melching, Otmar Scherzer
We present an approach for variational regularization of inverse and imaging problems for recovering functions with values in a set of vectors. We introduce regularization function…
A range condition for polyconvex variational regularization
Clemens Kirisits, Otmar Scherzer
In the context of convex variational regularization it is a known result that, under suitable differentiability assumptions, source conditions in the form of variational inequaliti…
