A Parallel Douglas Rachford Algorithm for Minimizing ROF-like Functionals on Images with Values in Symmetric Hadamard Manifolds
Ronny Bergmann, Johannes Persch, Gabriele Steidl
We are interested in restoring images having values in a symmetric Hadamard manifold by minimizing a functional with a quadratic data term and a total variation like regularizing t…
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…
Restoration of Manifold-Valued Images by Half-Quadratic Minimization
Ronny Bergmann, Raymond H. Chan, Ralf Hielscher +2
The paper addresses the generalization of the half-quadratic minimization method for the restoration of images having values in a complete Riemannian manifold. We recall the half-q…
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…
