A variational non-linear constrained model for the inversion of FDEM data
Alessandro Buccini, Patricia Díaz de Alba
Reconstructing the structure of the soil using non-invasive techniques is a very relevant problem in many scientific fields, like geophysics and archaeology. This can be done, for…
Graph Laplacian for image deblurring
Davide Bianchi, Alessandro Buccini, Marco Donatelli +1
Image deblurring is relevant in many fields of science and engineering. To solve this problem, many different approaches have been proposed and among the various methods, variation…
Generalized Structure Preserving Preconditioners for Frame-Based Image Deblurring
Davide Bianchi, Alessandro Buccini
We are interested in fast and stable iterative regularization methods for image deblurring problems with space invariant blur. The associated coefficient matrix has a Block Toeplit…
Iterated fractional Tikhonov regularization
Davide Bianchi, Alessandro Buccini, Marco Donatelli +1
Fractional Tikhonov regularization methods have been recently proposed to reduce the oversmoothing property of the Tikhonov regularization in standard form, in order to preserve th…
