A Shearlets-based Edge Identification Algorithem for Infrared Image

open access: yes, 2013
A shearlets-based edge identification algorithem for infrared image is proposed. The algorithem demonstrates the performance of edge detection based on shearlets, combines with the edge hysteresis thresholding, designs steps of edge detection, which is ...

Texture Classification and Retrieval Using Shearlets and Linear Regression

open access: yes, 2015
Statistical modeling of wavelet subbands has frequently been used for image recognition and retrieval. However, traditional wavelets are unsuitable for use with images containing distributed discontinuities, such as edges. Shearlets are a newly developed

On Quaternion Shearlet Transforms

open access: yes, 2018
In this paper, we introduce the notion of quaternion shearlet transform- which is an extension of the ordinary shearlet transform. Firstly, we study the fundamental properties of quaternion shearlet transforms and then establish some basic results including Moyal's and inversion formulae.

A nonsmooth regularization approach based on shearlets for Poisson noise removal in ROI tomography

open access: yes, 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.

Analyse von Shearlet-Coorbit-Räumen

open access: yes, 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
