Nonseparable Shearlet Transform

IEEE Transactions on Image Processing, 2013
Over the past few years, various representation systems which sparsely approximate functions governed by anisotropic features, such as edges in images, have been proposed. Alongside the theoretical development of these systems, algorithmic realizations of the associated transforms are provided.

Abstract Shearlet Transform [PDF]

Bulletin of the Belgian Mathematical Society - Simon Stevin, 2015
Approximately ten years ago the generalization of wavelets to shearlets started its development. This paper extends shearlets (introduced in 2005 to find efficient extensions for the classical wavelet transform, see among others \textit{G. Kutyniok} and \textit{D. Labate} [``Construction of regular and irregular shearlet frames'', J.

A Reverberation Noise Suppression Method of Sonar Image Based on Shearlet Transform

IEEE Sensors Journal, 2023
A sonar image affected by reverberation noise would generate serious speckle noise in the image, which causes great trouble for the later sonar image target segmentation and detection. Therefore, noise suppression is a crucial preprocessing technique for

Multivariate time series forecasting method based on nonlinear spiking neural P systems and non-subsampled shearlet transform

Neural Networks, 2022
Multivariate time series forecasting remains a challenging task because of its nonlinear, non-stationary, high-dimensional, and spatial-temporal characteristics, along with the dependence between variables.

Automatic Registration Algorithm for SAR and Optical Images Based on Shearlet and Sparse Representation

IEEE Geoscience and Remote Sensing Letters, 2023
The registration of synthetic aperture radar (SAR) and optical images is still a challenging task due to the influence of the potential nonlinear intensity differences and severe speckle noise.
