A Convolution-Based Shearlet Transform in Free Metaplectic Domains

open access: yesJournal of Mathematics, 2021
The free metaplectic transformation (FMT) is a multidimensional integral transform that encompasses a broader range of integral transforms, from the classical Fourier to the more recent linear canonical transforms. The aim of this study is to introduce a

Remote Sensing Image Denoising Based on Gaussian Curvature and Shearlet Transform

open access: yesIEEE Access, 2023
Model-based image denoising methods are well suited for use as image processors in remote sensing systems such as satellites due to their well-developed mathematical theory and low computational cost, but these methods can often only deal with a single ...

Image interpolation using Shearlet based iterative refinement [PDF]

open access: yes, 2013
This paper proposes an image interpolation algorithm exploiting sparse representation for natural images. It involves three main steps: (a) obtaining an initial estimate of the high resolution image using linear methods like FIR filtering, (b) promoting ...

Recent Progress in Shearlet Theory: Systematic Construction of Shearlet Dilation Groups, Characterization of Wavefront Sets, and New Embeddings [PDF]

open access: yes, 2016
The class of generalized shearlet dilation groups has recently been developed to allow the unified treatment of various shearlet groups and associated shearlet transforms that had previously been studied on a case-by-case basis.

Otherness feature extraction method for underground image based on Shearlet transform

open access: yesGong-kuang zidonghua, 2016
For the problem that face images collected underground are susceptible to dust interference and most feature extraction methods are sensitive to noise, an otherness feature extraction method for underground image based on Shearlet transform was proposed.
