A panorama on multiscale geometric representations, intertwining spatial, directional and frequency selectivity
The richness of natural images makes the quest for optimal representations in image
processing and computer vision challenging. The latter observation has not prevented the …

Scale-space anisotropic total variation for limited angle tomography
This paper addresses streak reduction in limited angle tomography. Although the iterative
reweighted total variation (wTV) algorithm reduces small streaks well, it is rather inept at …
