Space-Variant Total Variation boosted by learning techniques in few-view tomographic imaging

no code implementations25 Apr 2024 Elena Morotti, Davide Evangelista, Andrea Sebastiani, Elena Loli Piccolomini

This paper focuses on the development of a space-variant regularization model for solving an under-determined linear inverse problem.

Denoising Image Reconstruction

Ambiguity in solving imaging inverse problems with deep learning based operators

no code implementations31 May 2023 Davide Evangelista, Elena Morotti, Elena Loli Piccolomini, James Nagy

Numerical experiments are performed to verify the accuracy and stability of the proposed approaches for image deblurring when unknown or not-quantified noise is present; the results confirm that they improve the network stability with respect to noise.

Image Embedding for Denoising Generative Models

1 code implementation30 Dec 2022 Andrea Asperti, Davide Evangelista, Samuele Marro, Fabio Merizzi

Denoising Diffusion models are gaining increasing popularity in the field of generative modeling for several reasons, including the simple and stable training, the excellent generative quality, and the solid probabilistic foundation.

Denoising Image Generation

To be or not to be stable, that is the question: understanding neural networks for inverse problems

2 code implementations24 Nov 2022 Davide Evangelista, James Nagy, Elena Morotti, Elena Loli Piccolomini

The solution of linear inverse problems arising, for example, in signal and image processing is a challenging problem since the ill-conditioning amplifies, in the solution, the noise present in the data.
