DIVA: Deep Unfolded Network from Quantum Interactive Patches for Image Restoration

no code implementations31 Dec 2022 Sayantan Dutta, Adrian Basarab, Bertrand Georgeot, Denis Kouamé

This paper presents a deep neural network called DIVA unfolding a baseline adaptive denoising algorithm (De-QuIP), relying on the theory of quantum many-body physics.

Plug-and-Play Quantum Adaptive Denoiser for Deconvolving Poisson Noisy Images

1 code implementation1 Jul 2021 Sayantan Dutta, Adrian Basarab, Bertrand Georgeot, Denis Kouamé

A new Plug-and-Play (PnP) alternating direction of multipliers (ADMM) scheme is proposed in this paper, by embedding a recently introduced adaptive denoiser using the Schroedinger equation's solutions of quantum physics.

Large amplitude electromagnetic solitons in a fully relativistic magnetized electron-positron-pair plasma

no code implementations13 May 2020 Gadadhar Banerjee, Sayantan Dutta, A. P. Misra

Nonlinear propagation of purely stationary large amplitude electromagnetic (EM) solitary waves in a magnetized electron-positron (EP) plasma is studied using a fully relativistic two-fluid hydrodynamic model which accounts for physical regimes of both weakly relativistic $(P\ll nmc^2)$ and ultrarelativistic $(P\gg nmc^2)$ random thermal energies.

Quantum mechanics-based signal and image representation: application to denoising

no code implementations2 Apr 2020 Sayantan Dutta, Adrian Basarab, Bertrand Georgeot, Denis Kouamé

Decomposition of digital signals and images into other basis or dictionaries than time or space domains is a very common approach in signal and image processing and analysis.
