Nazarov Uncertainty Principle for Continuous Modulated Shearlet Transform on Euclidean Motion Group

International Journal of Scientific and Research Publications
Nazarov uncertainty principle has been proved for the Fourier transform and the continuous modulated shearlet transform on the Euclidean motion group. These principles can be used to deduce the Nazarov uncertainty principle for the well-known transforms ...

Hybrid regularization for compressed sensing MRI: Exploiting shearlet transform and group-sparsity total variation

2017 20th International Conference on Information Fusion (Fusion), 2017
Magnetic resonance imaging (MRI) has been extensively used in clinical practice but suffers from long data acquisition time. Following the success of compressed sensing (CS) theory, many efforts have been made to accurately reconstruct MR images from undersampled k-space measurements and therefore dramatically reduce MRI scan time.

Lieb's Inequality for Continuous Modulated Shearlet Transform on LCA Groups

Tuijin Jishu/Journal of Propulsion Technology, 2023
We have proved a version of Lieb's inequality for continuous modulated shearlet transform on locally compact Abelian (LCA) groups. An alternative proof for the inequality has also been provided using Riesz-Thorin interpolation theorem.
