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.

The Discrete Shearlet Transform: A New Directional Transform and Compactly Supported Shearlet Frames

IEEE Transactions on Image Processing, 2010
It is now widely acknowledged that analyzing the intrinsic geometrical features of the underlying image is essential in many applications including image processing. In order to achieve this, several directional image representation schemes have been proposed.

Uncertainty Principles For The Continuous Quaternion Shearlet Transform

Advances in Applied Clifford Algebras, 2019
In this paper, authors have studied some novel uncertainty principles for the continuous quaternion shearlet transform using the machinery of quaternion convolution, quaternion Fourier transform and operator theory. Besides, the fundamental properties including the Parseval's and reconstruction formulae, the Heisenberg-type uncertainty principles are ...

3-D Discrete Shearlet Transform and Video Processing

IEEE Transactions on Image Processing, 2012
In this paper, we introduce a digital implementation of the 3-D shearlet transform and illustrate its application to problems of video denoising and enhancement. The shearlet representation is a multiscale pyramid of well-localized waveforms defined at various locations and orientations, which was introduced to overcome the limitations of traditional ...

Continuous Modulated Shearlet Transform

Advances in Pure and Applied Mathematics, 2022
Summary: We generalize the well-known transforms such as short-time Fourier transform, wavelet transform and shearlet transform and refer it as Continuous Modulated Shearlet Transform. Important properties like Plancherel formula and inversion formula have been investigated. Uncertainty inequalities associated with this transform are presented.

SHEARLET TRANSFORMS AND DIRECTIONAL REGULARITIES

International Journal of Wavelets, Multiresolution and Information Processing, 2010
In an effort to characterize uniform and pointwise Hölder regularities, we obtain necessary decay rates and sufficient decay rates of continuous and discrete shearlet transform across scales. They are the same rates as those of the Hart Smith and continuous curvelet transforms.
