On Regularization via Frame Decompositions with Applications in Tomography
Simon Hubmer, Ronny Ramlau, Lukas Weissinger
In this paper, we consider linear ill-posed problems in Hilbert spaces and their regularization via frame decompositions, which are generalizations of the singular-value decomposit…
Robust and bias-free localization of individual fixed dipole emitters achieving the Cramér Rao bound
Fabian Hinterer, Magdalena C. Schneider, Simon Hubmer +5
Single molecule localization microscopy has the potential to resolve structural details of biological samples at the nanometer length scale. However, to fully exploit the resolutio…
Challenges for Optical Flow Estimates in Elastography
Ekaterina Sherina, Lisa Krainz, Simon Hubmer +2
In this paper, we consider visualization of displacement fields via optical flow methods in elastographic experiments consisting of a static compression of a sample. We propose an…
Phase-contrast THz-CT for non-destructive testing
Peter Fosodeder, Simon Hubmer, Alexander Ploier +3
A new approach for image reconstruction in THz computed tomography (THz-CT) is presented. Based on a geometrical optics model containing the THz signal amplitude and phase, a novel…
