A hybrid proximal generalized conditional gradient method and application to total variation parameter learning
Kristian Bredies, Enis Chenchene, Alireza Hosseini
In this paper we present a new method for solving optimization problems involving the sum of two proper, convex, lower semicontinuous functions, one of which has Lipschitz continuo…
A Second-Order TGV Discretization with Rotational Invariance Property
Alireza Hosseini, Kristian Bredies
In this work, we propose a new discretization for second-order total generalized variation (TGV) with some distinct properties compared to existing discrete formulations. The intro…
Compressed MRI Reconstruction Exploiting a Rotation-Invariant Total Variation Discretization
Erfan Ebrahim Esfahani, Alireza Hosseini
Inspired by the first-order method of Malitsky and Pock, we propose a new variational framework for compressed MR image reconstruction which introduces the application of a rotatio…
A Regularization Term Based on a Discrete Total Variation for Mathematical Image Processing
Alireza Hosseini
In this paper, a new regularization term is proposed to solve mathematical image problems. By using difference operators in the four directions; horizontal, vertical and two diagon…
