Recent Advances in Denoising of Manifold-Valued Images
Ronny Bergmann, Friederike Laus, Johannes Persch +1
Modern signal and image acquisition systems are able to capture data that is no longer real-valued, but may take values on a manifold. However, whenever measurements are taken, no…
Multivariate Myriad Filters based on Parameter Estimation of Student- Distributions
Friederike Laus, Gabriele Steidl
The contribution of this study is twofold: First, we propose an efficient algorithm for the computation of the (weighted) maximum likelihood estimators for the parameters of the mu…
On the Atomic Decomposition of Coorbit Spaces with Non-Integrable Kernel
Stephan Dahlke, Filippo De Mari, Ernesto De Vito +4
This paper ist concerned with recent progress in the context of coorbit space theory. Based on a square integrable group representation, the coorbit theory provides new families of…
Linkage between piecewise constant Mumford-Shah model and ROF model and its virtue in image segmentation
Xiaohao Cai, Raymond Chan, Carola-Bibiane Schonlieb +2
The piecewise constant Mumford-Shah (PCMS) model and the Rudin-Osher-Fatemi (ROF) model are two important variational models in image segmentation and image restoration, respective…
Regularization of Inverse Problems via Time Discrete Geodesics in Image Spaces
Sebastian Neumayer, Johannes Persch, Gabriele Steidl
This paper addresses the solution of inverse problems in imaging given an additional reference image. We combine a modification of the discrete geodesic path model for image metamo…
