Silvia Gazzola's Projects

auto_tikhonov_tv

MATLAB functions for solving linear inverse problems through a combination of Tikhonov and TV regularization terms, subject to a constraint on the noise affecting the data. The Tikhonov regularization term is weighted by a regularization parameter that can be set adaptively.

bilevel_adaptive_parameterchoice

MATLAB functions implementing and testing the methods described in: Silvia Gazzola and Malena Sabate Landman, Adaptive Regularization Parameter Choice Rules for Large-Scale Problems, arXiv 1907.05666, 2019. To soon appear in GAMM-Mitteilungen. To be used in connection with IR Tools.

edgeenhancement

MATLAB functions and script implementing the method described in the linked paper. To be used as an add-on to IR Tools; uses some functions from AIR Tools II.

edgeenhancingfgk

New solvers based on Flexible Golub-Kahan for edge enhancement in inverse problems in imaging.

irtools

MATLAB package of iterative regularization methods and large-scale test problems. This software is described in the paper "IR Tools: A MATLAB Package of Iterative Regularization Methods and Large-Scale Test Problems" that will be published in Numerical Algorithms, 2018.
