Variation for Piecewise Constant Functions on Triangular Meshes with Applications in Imaging
(Journal article, 2023)We propose a novel discrete concept for the total generalized variation (TGV), which was originally derived to reduce the staircasing effect in classical total variation regularization, in image denoising problems. We ... -
Variational image regularization with Euler's elastica using a discrete gradient scheme
(Journal article; Peer reviewed, 2018)This paper concerns an optimization algorithm for unconstrained nonconvex problems where the objective function has sparse connections between the unknowns. The algorithm is based on applying a dissipation preserving ...
