Variational image regularization with Euler's elastica using a discrete gradient scheme
Ringholm, Torbjørn; Lazic, Jasmina; Schönlieb, Carola-Bibiane (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 ...
