A nonsmooth regularization approach based on shearlets for Poisson noise removal in ROI tomography
, 2018 Due to its potential to lower exposure to X-ray radiation and reduce the scanning time, region-of-interest (ROI) computed tomography (CT) is particularly appealing for a wide range of biomedical applications.

Wavelet and frame theory: frame bound gaps, generalized shearlets, Grassmannian fusion frames, and p-adic wavelets [PDF]
, 2009 The first wavelet system was discovered by Alfréd Haar one hundred years ago. Since then the field has grown enormously. In 1952, Richard Duffin and Albert Schaeffer synthesized the earlier ideas of a number of illustrious mathematicians into a

Analyse von Shearlet-Coorbit-Räumen
, 2018 Coorbit theory provides a framework for the study of approximation theoretic properties of certain elementary building blocks and to analyze properties of functions by considering the decay behavior of their associated wavelet transform. This transform is based on a representation of a group and properties of the group are decisive for the structure of
