Analysis and Application of a non-local Hessian
Jan Lellmann, Konstantinos Papafitsoros, Carola Schoenlieb +1
In this work we introduce a formulation for a non-local Hessian that combines the ideas of higher-order and non-local regularization for image restoration, extending the idea of no…
Solving QVIs for Image Restoration with Adaptive Constraint Sets
Frank Lenzen, Jan Lellmann, Florian Becker +1
We consider a class of quasi-variational inequalities (QVIs) for adaptive image restoration, where the adaptivity is described via solution-dependent constraint sets. In previous w…
Imaging with Kantorovich-Rubinstein discrepancy
Jan Lellmann, Dirk A. Lorenz, Carola Schönlieb +1
We propose the use of the Kantorovich-Rubinstein norm from optimal transport in imaging problems. In particular, we discuss a variational regularisation model endowed with a Kantor…
A Comparative Study of Modern Inference Techniques for Structured Discrete Energy Minimization Problems
Jörg H. Kappes, Bjoern Andres, Fred A. Hamprecht +10
Szeliski et al. published an influential study in 2006 on energy minimization methods for Markov Random Fields (MRF). This study provided valuable insights in choosing the best opt…
