Efficient TV regularization of large-scale linear inverse problems via the SCD semismooth* Newton method with applications in tomography
Helmut Gfrerer, Simon Hubmer, Stefan Kindermann +3
In this paper, we consider the efficient numerical minimization of Tikhonov functionals resulting from total-variation (TV) regularization of linear inverse problems. Since the TV…
On a PDE-based material parameter identification problem with contact constraints
Simon Hubmer, Stefan Kindermann, Ekaterina Sherina
We consider the identification of a scalar coefficient in a PDE-based parameter estimation problem with contact constraints. The considered problem can be used as an idealized mode…
A Frame Decomposition of the Funk-Radon Transform
Michael Quellmalz, Lukas Weissinger, Simon Hubmer +1
The Funk-Radon transform assigns to a function defined on the unit sphere its integrals along all great circles of the sphere. In this paper, we consider a frame decomposition of t…
