Local Spatio-Temporal Representation Using the 3D Shearlet Transform (STSIP)

, 2017
In this work we address the problem of analyzing video sequences and of representing meaningful space-time points of interest by using the 3D shearlet transform.

A unified comparative framework for multiscale geometric transforms in SAR and multispectral satellite image analysis

Frontiers in Remote Sensing
Satellite image analysis is essential for remote sensing analysis. Two types of data are captured via satellite: Synthetic Aperture Radar (SAR) imagery (which has structure) and multispectral imagery (which contains spectral information), so ...

Efficient multiscale and multidirectional representation of 3D Data using the 3D discrete shearlet transform

, 2011
In recent years, there has been a lot of interest in multiresolution representations that also perform a multidirectional analysis. These representations often yield very sparse representation for multidimensional data. The shearlet representation, which

Analysis of Singularities and Edge Detection using the Shearlet Transform

, 2009
The continuous curvelet and shearlet transforms have recently been shown to be much more effective than the traditional wavelet transform in dealing with the set of discontinuities of functions and distributions.

Hyperspectral image classification using non-subsampled shearlet transform

, 2017
: In this paper a new supervised classification method for hyperspectral image is introduced. In the proposed method first, 2D non-subsampled shearlet transform is applied to each spectral band of hyperspectral images.
