Over the last 20 years, multiscale methods and wavelets have revolutionized the field of applied mathematics by providing an efficient means for encoding isotropic phenomena. Directional multiscale systems, particularly shearlets, are now having the same dramatic impact on the encoding of multivariate signals.

In this chapter, we will provide a comprehensive overview of shearlet coorbit theory. We will present an almost self-contained introduction into coorbit theory which is the basis for all our investigations. We also discuss the group theoretical background of the continuous shearlet transform, and we explain how the shearlet transform can be combined ...

Shearlets on bounded domains and analysis of singularities using compactly supported shearlets
2016Die vorliegende Arbeit untersucht und erweitert die Theorie der Shearletsysteme. Diese Systeme wurden seit ihrer Einführung in einer Vielzahl von Anwendungen in der Signal- und Bildverarbeitung und weiteren verwandten Gebieten eingesetzt. Die Resultate dieser Arbeit lassen sich zwei Bereichen zuordnen.

The aim of this report is a self-contained overview on shearlets, a new multiscale method emerged in the last decade to overcome some of the limitation of traditional multiscale methods, like wavelets. Shearlets are obtained by translating, dilating and shearing a single mother function.
