Shearlets on bounded domains and analysis of singularities using compactly supported shearlets

open access: yes, 2016
In this thesis we discuss and extend the theory of shearlet systems. These systems were introduced in [LLKW05, GKL06] and have found a multitude of applications in signaland image processing and related fields since then.

Edges and Corners With Shearlets

IEEE Transactions on Image Processing, 2015
Shearlets are a relatively new and very effective multi-scale framework for signal analysis. Contrary to the traditional wavelets, shearlets are capable to efficiently capture the anisotropic information in multivariate problem classes. Therefore, shearlets can be seen as the valid choice for multi-scale analysis and detection of directional sensitive ...

Shearlets: Theory and Applications

GAMM-Mitteilungen, 2014
AbstractMany important problem classes are governed by anisotropic features such as singularities concentrated on lower dimensional embedded manifolds, for instance, edges in images or shock fronts in solutions of transport dominated equations. While the ability to reliably capture and sparsely represent anisotropic structures is obviously the more ...

Microlocal Analysis and Characterization of Sobolev Wavefront Sets Using Shearlets

Constructive approximation, 2020
Sobolev wavefront sets and 2-microlocal spaces play a key role in describing and analyzing the singularities of distributions in microlocal analysis and solutions of partial differential equations.
