Multi-Channel Potts-Based Reconstruction for Multi-Spectral Computed Tomography

no code implementations12 Sep 2020 Lukas Kiefer, Stefania Petra, Martin Storath, Andreas Weinmann

We consider reconstructing multi-channel images from measurements performed by photon-counting and energy-discriminating detectors in the setting of multi-spectral X-ray computed tomography (CT).

Computed Tomography (CT)

Iterative Potts minimization for the recovery of signals with discontinuities from indirect measurements -- the multivariate case

no code implementations3 Dec 2018 Lukas Kiefer, Martin Storath, Andreas Weinmann

A frequent task is to find the segments of the signal or image which corresponds to finding the discontinuities or jumps in the data.
