Inhomogeneous shearlet coorbit spaces [PDF]
arXiv, 2017 In this paper we establish inhomogeneous coorbit spaces related to the continuous shearlet transform and the weighted Lebesgue spaces $L_{p,v}, p\geq 1,$ for certain weights $v$. We present an inhomogeneous shearlet frame for $L_2(\mathbb{R}^d)$ which gives rise to a reproducing kernel $R_\mathfrak{F}$ that is not contained in the space $\mathcal{A}_{1,

DRST: Deep Residual Shearlet Transform for Densely Sampled Light Field Reconstruction [PDF]
arXiv, 2020 The Image-Based Rendering (IBR) approach using Shearlet Transform (ST) is one of the most effective methods for Densely-Sampled Light Field (DSLF) reconstruction. The ST-based DSLF reconstruction typically relies on an iterative thresholding algorithm for Epipolar-Plane Image (EPI) sparse regularization in shearlet domain, involving dozens of ...

Construction of Compactly Supported Shearlet Frames [PDF]
arXiv, 2010 Shearlet tight frames have been extensively studied during the last years due to their optimal approximation properties of cartoon-like images and their unified treatment of the continuum and digital setting. However, these studies only concerned shearlet tight frames generated by a band-limited shearlet, whereas for practical purposes compact support ...

Dualizable Shearlet Frames and Sparse Approximation [PDF]
arXiv, 2014 Shearlet systems have been introduced as directional representation systems, which provide optimally sparse approximations of a certain model class of functions governed by anisotropic features while allowing faithful numerical realizations by a unified treatment of the continuum and digital realm. They are redundant systems, and their frame properties

Continuous Shearlet Frames and Resolution of the Wavefront Set [PDF]
arXiv, 2009 In recent years directional multiscale transformations like the curvelet- or shearlet transformation have gained considerable attention. The reason for this is that these transforms are - unlike more traditional transforms like wavelets - able to efficiently handle data with features along edges. The main result in [G. Kutyniok, D.

Digital Shearlet Transforms [PDF]
arXiv, 2011 Over the past years, various representation systems which sparsely approximate functions governed by anisotropic features such as edges in images have been proposed. We exemplarily mention the systems of contourlets, curvelets, and shearlets. Alongside the theoretical development of these systems, algorithmic realizations of the associated transforms ...
