Enhanced Offshore Wind Farm Geophysical Surveys: Shearlet-Sparse Regularization in Multi-Channel Predictive Deconvolution

open access: yesRemote Sensing
This study introduces a novel multi-channel predictive deconvolution method enhanced by Shearlet-based sparse regularization, aimed at improving the accuracy and stability of subsurface seismic imaging, particularly in offshore wind farm site assessments.

Detecting Spatio-Temporally Interest Points Using the Shearlet Transform

open access: yes, 2017
In this paper we address the problem of detecting spatio-temporal interest points in video sequences and we introduce a novel detection algorithm based on the three-dimensional shearlet transform.

Characterization of Piecewise-Smooth Surfaces Using the 3D Continuous Shearlet Transform

open access: yes, 2011
One of the most striking features of the Continuous Shearlet Transform is its ability to precisely characterize the set of singularities of multivariable functions through its decay at fine scales.

Comparing Undecimated Wavelet, Nonsubsampled Contourlet and Shearlet for Sar Images Despeckling

open access: yesMajlesi Journal of Electrical Engineering
Synthetic Aperture Radar (SAR) images suffer of multiplicative speckle noise, which damages the radiometric resolution of SAR images and makes the data interpretation difficult.

Analysis and detection of surface discontinuities using the 3D continuous shearlet transform

open access: yes, 2011
Directional multiscale transforms such as the shearlet transform have emerged in recent years for their ability to capture the geometrical information associated with the singularity sets of bivariate functions and distributions. One of the most striking

A New Shearlet Framework for Image Denoising

open access: yesIranian Journal of Electrical and Electronic Engineering, 2016
Traditional noise removal methods like Non-Local Means create spurious boundaries inside regular zones. Visushrink removes too many coefficients and yields recovered images that are overly smoothed.
