Unrolled three-operator splitting for parameter-map learning in Low Dose X-ray CT reconstruction
Kofler, A; Altekrüger, F; Ba, FA; Kolbitsch, C; Papoutsellis, E; Schote, D; Sirotenko, C; Zimmermann, FF; Papafitsoros, K (arXiv, 2023-04-17)We propose a method for fast and automatic estimation of spatially dependent regularization maps for total variation-based (TV) tomography reconstruction. The estimation is based on two distinct sub-networks, with the first ...
