Position-Blind Ptychography: Viability of image reconstruction via data-driven variational inference
Simon Welker, Lorenz Kuger, Tim Roith +4
In this work, we present and investigate the novel blind inverse problem of position-blind ptychography, i.e., ptychographic phase retrieval without any knowledge of scan positions…
Analysis of Primal-Dual Langevin Algorithms
Martin Burger, Matthias J. Ehrhardt, Lorenz Kuger +1
We analyze a recently proposed class of algorithms for the problem of sampling from probability distributions in with a Lebesgue density of the form $μ^\ast…
Proximal Langevin Sampling With Inexact Proximal Mapping
Matthias J. Ehrhardt, Lorenz Kuger, Carola-Bibiane Schönlieb
In order to solve tasks like uncertainty quantification or hypothesis tests in Bayesian imaging inverse problems, we often have to draw samples from the arising posterior distribut…
On multiple scattering in Compton scattering tomography and its impact on fan-beam CT
Lorenz Kuger, Gael Rigaud
The recent development of energy-resolving scintillation crystals opens the way to new types of applications and imaging systems. In the context of computerized tomography (CT), it…
