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 ...

Oberwolfach Reports, 2011 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.

, 2014 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.

Shearlets and their applications
AIP Conference Proceedings, 2012 Shearlets were introduced as means to sparsely encode anisotropic singularities of multivariate data while providing a unified treatment of the continuous and digital realm. In this chapter, recent results on compactly supported shearlet systems will be presented, in particular, showing that these shearlet frames provide optimally sparse approximations

Shearlets on bounded domains and analysis of singularities using compactly supported shearlets
, 2016 Die 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.

Optimally Sparse Multidimensional Representation Using Shearlets
SIAM Journal on Mathematical Analysis, 2007 n this paper we show that shearlets, an affine-like system of functions recently introduced by the authors and their collaborators, are essentially optimal in representing 2-dimensional functions f which are $C^2$ except for discontinuities along $C^2 ...

A Shearlets-Based Method for Rain Removal from Single Images
Applied Sciences (Switzerland), 2019 This work focuses on the problem of rain removal from a single image. The directional multilevel system, Shearlets, is used to describe the intrinsic directional and structure sparse priors of rain streaks and the background layer.

Continuous Modulated Shearlet Transform
Advances in Pure and Applied Mathematics, 2022Summary: We generalize the well-known transforms such as short-time Fourier transform, wavelet transform and shearlet transform and refer it as Continuous Modulated Shearlet Transform. Important properties like Plancherel formula and inversion formula have been investigated. Uncertainty inequalities associated with this transform are presented.
