Inverse Scale Space Decomposition
Marie Foged Schmidt, Martin Benning, Carola-Bibiane Schönlieb
We investigate the inverse scale space flow as a decomposition method for decomposing data into generalised singular vectors. We show that the inverse scale space flow, based on co…
A Variational Model for Joint Motion Estimation and Image Reconstruction
Martin Burger, Hendrik Dirks, Carola-Bibiane Schönlieb
The aim of this paper is to derive and analyze a variational model for the joint estimation of motion and reconstruction of image sequences, which is based on a time-continuous Eul…
The use of discrete gradient methods for total variation type regularization problems in image processing
V Grimm, R I McLachlan, D McLaren +2
Discrete gradient methods are well-known methods of Geometric Numerical Integration, which preserve the dissipation of gradient systems. The preservation of the dissipation of a sy…
Explorations on anisotropic regularisation of dynamic inverse problems by bilevel optimisation
Martin Benning, Carola-Bibiane Schönlieb, Tuomo Valkonen +1
We explore anisotropic regularisation methods in the spirit of [Holler & Kunisch, 14]. Based on ground truth data, we propose a bilevel optimisation strategy to compute the optimal…
