A Nonlocal Graph-PDE and Higher-Order Geometric Integration for Image Labeling
Dmitrij Sitenko, Bastian Boll, Christoph Schnörr
This paper introduces a novel nonlocal partial difference equation (G-PDE) for labeling metric data on graphs. The G-PDE is derived as nonlocal reparametrization of the assignment…
Learning Adaptive Regularization for Image Labeling Using Geometric Assignment
Ruben Hühnerbein, Fabrizio Savarino, Stefania Petra +1
We study the inverse problem of model parameter learning for pixelwise image labeling, using the linear assignment flow and training data with ground truth. This is accomplished by…
Symmetry-free SDP Relaxations for Affine Subspace Clustering
Francesco Silvestri, Gerhard Reinelt, Christoph Schnörr
We consider clustering problems where the goal is to determine an optimal partition of a given point set in Euclidean space in terms of a collection of affine subspaces. While ther…
Second-Order Recursive Filtering on the Rigid-Motion Lie Group SE(3) Based on Nonlinear Observations
Johannes Berger, Frank Lenzen, Florian Becker +2
Camera motion estimation from observed scene features is an important task in image processing to increase the accuracy of many methods, e.g. optical flow and structure-from-motion…
Solving QVIs for Image Restoration with Adaptive Constraint Sets
Frank Lenzen, Jan Lellmann, Florian Becker +1
We consider a class of quasi-variational inequalities (QVIs) for adaptive image restoration, where the adaptivity is described via solution-dependent constraint sets. In previous w…
Convex Variational Image Restoration with Histogram Priors
Paul Swoboda, Christoph Schnörr
We present a novel variational approach to image restoration (e.g., denoising, inpainting, labeling) that enables to complement established variational approaches with a histogram-…
