A Second Order Non-Smooth Variational Model for Restoring Manifold-Valued Images
Miroslav Bačák, Ronny Bergmann, Gabriele Steidl +1
We introduce a new non-smooth variational model for the restoration of manifold-valued data which includes second order differences in the regularization term. While such models we…
Exact algorithms for -TV regularization of real-valued or circle-valued signals
Martin Storath, Andreas Weinmann, Michael Unser
We consider -TV regularization of univariate signals with values on the real line or on the unit circle. While the real data space leads to a convex optimization problem, the…
A Second Order TV-type Approach for Inpainting and Denoising Higher Dimensional Combined Cyclic and Vector Space Data
Ronny Bergmann, Andreas Weinmann
In this paper we consider denoising and inpainting problems for higher dimensional combined cyclic and linear space valued data. These kind of data appear when dealing with nonline…
