The Uncertainty Principle:Group Theoretic Approach, Possible Minimizers and Scale-Space Properties
uncertainty principles minimal uncertainty states affine weyl-heisenberg group scale-space
2010/1/7
The uncertainty principle is a fundamental concept in the context of signal and image processing, just as much as it has been in the framework of physics and more recently in harmonic analysis. Uncert...
Gabor Feature Space Diffusion via the Minimal Weighted Area Method

Astronauts are not the only ones earning wings on the International Space Station. Butterflies emerged aboard the station recently, to the delight of science students across the country. That experime...
A Note on the Iterative MRI Reconstruction from Nonuniform k-Space Data
the Iterative MRI Nonuniform k-Space Data
2009/9/7
In magnetic resonance imaging (MRI), methods that use a non-Cartesian grid in k-space are becoming increasingly important. In this paper, we use a recently proposed implicit discretisation scheme whic...
Reordering for Improved Constrained Reconstruction from Undersampled k-Space Data
Improved Constrained Reconstruction Undersampled k-Space Data
2009/9/4
Recently, there has been a significant interest in applying reconstruction techniques, like constrained reconstruction or compressed sampling methods, to undersampled k-space data in MRI. Here, we pro...
