Diffraction Tomography for a Generalized Incident Field
Clemens Kirisits, Noemi Naujoks, Otmar Scherzer
Diffraction tomography is an inverse scattering technique used to reconstruct the spatial distribution of the material properties of a weakly scattering object. The object is expos…

Uncertainty Quantification for Scale-Space Blob Detection
Fabian Parzer, Clemens Kirisits, Otmar Scherzer
We consider the problem of blob detection for uncertain images, such as images that have to be inferred from noisy measurements. Extending recent work motivated by astronomical app…

Total Variation Denoising on Hexagonal Grids
Clemens Kirisits
This work combines three paradigms of image processing: i) the total variation approach to denoising, ii) the superior structure of hexagonal lattices, and iii) fast and exact grap…
