Introducing Image-Space Preconditioning in the Variational Formulation of MRI Reconstructions
Bastien Milani, Jean-Baptist Ledoux, Berk Can Acikgoz +1
The aim of the present article is to enrich the comprehension of iterative magnetic resonance imaging (MRI) reconstructions, including compressed sensing (CS) and iterative deep le…
Metaplectic Gabor frames of Wigner-Decomposable Distributions
Elena Cordero, Gianluca Giacchi
Metaplectic Wigner distributions generalize the most popular time-frequency representations, such as the short-time Fourier transform (STFT) and -Wigner distributions, using met…
Metaplectic Gabor Frames and Symplectic Analysis of Time-Frequency Spaces
Elena Cordero, Gianluca Giacchi
We introduce new frames, called \textit{metaplectic Gabor frames}, as natural generalizations of Gabor frames in the framework of metaplectic Wigner distributions. Namely, we devel…
On the determination of Lagrange Multipliers for a weighted LASSO problem using geometric and convex analysis techniques
Gianluca Giacchi, Bastien Milani, Benedetta Franchieschiello
Compressed Sensing (CS) encompasses a broad array of theoretical and applied techniques for recovering signals, given partial knowledge of their coefficients. Its applications span…
