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…
A mathematical approach towards THz tomography for non-destructive imaging
Simon Hubmer, Alexander Ploier, Ronny Ramlau +2
In this paper, we consider the imaging problem of terahertz (THz) tomography, in particular as it appears in non-destructive testing. We derive a nonlinear mathematical model descr…
Displacement field estimation from OCT images utilizing speckle information with applications in quantitative elastography
Ekaterina Sherina, Lisa Krainz, Simon Hubmer +2
In this paper, we consider the problem of estimating the internal displacement field of an object which is being subjected to a deformation, from Optical Coherence Tomography (OCT)…
A note on the minimization of a Tikhonov functional with -penalty
Fabian Hinterer, Simon Hubmer, Ronny Ramlau
In this paper, we consider the minimization of a Tikhonov functional with an penalty for solving linear inverse problems with sparsity constraints. One of the many approac…
A Conjugate-Gradient Approach to the Parameter Estimation Problem of Magnetic Resonance Advection Imaging
Simon Hubmer, Andreas Neubauer, Ronny Ramlau +1
We consider the inverse problem of estimating the spatially varying pulse wave velocity in blood vessels in the brain from dynamic MRI data, as it appears in the recently proposed…
