Analysis and Application of a non-local Hessian
Jan Lellmann, Konstantinos Papafitsoros, Carola Schoenlieb +1
In this work we introduce a formulation for a non-local Hessian that combines the ideas of higher-order and non-local regularization for image restoration, extending the idea of no…
Non-parametric Image Registration of Airborne LiDAR, Hyperspectral and Photographic Imagery of Forests
Juheon Lee, Xiaohao Cai, Carola-Bibiane Schonlieb +1
There is much current interest in using multi-sensor airborne remote sensing to monitor the structure and biodiversity of forests. This paper addresses the application of non-param…
Variational Depth from Focus Reconstruction
Michael Moeller, Martin Benning, Carola Schönlieb +1
This paper deals with the problem of reconstructing a depth map from a sequence of differently focused images, also known as depth from focus or shape from focus. We propose to sta…
Imaging with Kantorovich-Rubinstein discrepancy
Jan Lellmann, Dirk A. Lorenz, Carola Schönlieb +1
We propose the use of the Kantorovich-Rubinstein norm from optimal transport in imaging problems. In particular, we discuss a variational regularisation model endowed with a Kantor…
Dynamic sampling schemes for optimal noise learning under multiple nonsmooth constraints
Luca Calatroni, Juan Carlos De Los Reyes, Carola-Bibiane Schönlieb
We consider the bilevel optimisation approach proposed by De Los Reyes, Schönlieb (2013) for learning the optimal parameters in a Total Variation (TV) denoising model featuring for…
Total Variation Regularisation in Measurement and Image space for PET reconstruction
Martin Burger, Jahn Müller, Evangelos Papoutsellis +1
The aim of this paper is to test and analyze a novel technique for image reconstruction in positron emission tomography, which is based on (total variation) regularization on both…
