Inhomogeneous shearlet coorbit spaces [PDF]

open access: yesInternational Journal of Wavelets, Multiresolution and Information Processing, 2018
In this paper, we establish inhomogeneous coorbit spaces related to the continuous shearlet transform and the weighted Lebesgue spaces [Formula: see text] for certain weights [Formula: see text].

Shearlet-based loop filter

open access: yes2018 26th European Signal Processing Conference (EUSIPCO), 2022
S.141-145In video coding, in-loop filtering has attracted attention due to its increasing coding performances. In this paper the shearlet-based loop filter is proposed using a sparsifying transform, the shearlet transform, which can identify the ...

Bendlet Transform Based Adaptive Denoising Method for Microsection Images [PDF]

open access: yesEntropy, 2022
Magnetic resonance imaging (MRI) plays an important role in disease diagnosis. The noise that appears in MRI images is commonly governed by a Rician distribution. The bendlets system is a second-order shearlet transform with bent elements.

Digital shearlet transforms [PDF]

open access: yes, 2012
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.

Noise reduction by adaptive-SIN filtering for retinal OCT images [PDF]

open access: yesScientific Reports, 2021
Optical coherence tomography (OCT) images is widely used in ophthalmic examination, but their qualities are often affected by noises. Shearlet transform has shown its effectiveness in removing image noises because of its edge-preserving property and ...

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 ...
