Diffusion Graph Posterior Sampling for Nonlinear Inverse Problems with Application to Electrical Impedance Tomography
Giovanni S. Alberti, Damiana Lazzaro, Serena Morigi +2
Deep generative models have emerged as state-of-the-art for solving inverse problems, but applying them to inverse problems for PDEs, like electrical impedance tomography (EIT) rem…
Non-convex Super-resolution of OCT images via sparse representation
Gabriele Scrivanti, Luca Calatroni, Serena Morigi +2
We propose a non-convex variational model for the super-resolution of Optical Coherence Tomography (OCT) images of the murine eye, by enforcing sparsity with respect to suitable di…
Space-variant Generalized Gaussian Regularization for Image Restoration
Alessandro Lanza, Serena Morigi, Monica Pragliola +1
We propose a new space-variant regularization term for variational image restoration based on the assumption that the gradient magnitudes of the target image distribute locally acc…
Space-variant TV regularization for image restoration
Alessandro Lanza, Serena Morigi, Monica Pragliola +1
We propose two new variational models aimed to outperform the popular total variation (TV) model for image restoration with L and L fidelity terms. In particular, we introd…
