Priors with Coupled First and Second Order Differences for Manifold-Valued Image Processing
Ronny Bergmann, Jan Henrik Fitschen, Johannes Persch +1
Recently variational models with priors involving first and second order derivatives resp. differences were successfully applied for image restoration. There are several ways to in…
Strain Analysis by a Total Generalized Variation Regularized Optical Flow Model
Frank Balle, Tilmann Beck, Dietmar Eifler +3
In this paper we deal with the important problem of estimating the local strain tensor from a sequence of micro-structural images realized during deformation tests of engineering m…
Unsupervised Multi Class Segmentation of 3D Images with Intensity Inhomogeneities
Jan Henrik Fitschen, Katharina Losch, Gabriele Steidl
Intensity inhomogeneities in images constitute a considerable challenge in image segmentation. In this paper we propose a novel biconvex variational model to tackle this task. We c…
Iterative Multiplicative Filters for Data Labeling
Ronny Bergmann, Jan Henrik Fitschen, Johannes Persch +1
Based on an idea in [4] we propose a new iterative multiplicative filtering algorithm for label assignment matrices which can be used for the supervised partitioning of data. Start…
Transport between RGB Images Motivated by Dynamic Optimal Transport
Jan Henrik Fitschen, Friederike Laus, Gabriele Steidl
We propose two models for the interpolation between RGB images based on the dynamic optimal transport model of Benamou and Brenier [8]. While the application of dynamic optimal tra…
Removal of Curtaining Effects by a Variational Model with Directional Forward Differences
Jan Henrik Fitschen, Jianwei Ma, Sebastian Schuff
Focused ion beam (FIB) tomography provides high resolution volumetric images on a micro scale. However, due to the physical acquisition process the resulting images are often corru…
