Fast and Exact Least Absolute Deviations Line Fitting via Piecewise Affine Lower-Bounding
Stefan Volz, Martin Storath, Andreas Weinmann
Least-absolute-deviations (LAD) line fitting is robust to outliers but computationally more involved than least squares regression. Although the literature includes linear and near…
Degrees-of-freedom penalized piecewise regression
Stefan Volz, Martin Storath, Andreas Weinmann
Many popular piecewise regression models rely on minimizing a cost function on the model fit with a linear penalty on the number of segments. However, this penalty does not take in…
Variational Model-Based Reconstruction Techniques for Multi-Patch Data in Magnetic Particle Imaging
Vladyslav Gapyak, Thomas März, Andreas Weinmann
Magnetic Particle Imaging is an emerging imaging modality through which it is possible to detect tracers containing superparamagnetic nanoparticles. The exposure of the particles t…
Automatic Individual Identification of Patterned Solitary Species Based on Unlabeled Video Data
Vanessa Suessle, Mimi Arandjelovic, Ammie K. Kalan +17
The manual processing and analysis of videos from camera traps is time-consuming and includes several steps, ranging from the filtering of falsely triggered footage to identifying…
Smoothing splines for discontinuous signals
Martin Storath, Andreas Weinmann
Smoothing splines are twice differentiable by construction, so they cannot capture potential discontinuities in the underlying signal. In this work, we consider a special case of t…
Multi-Channel Potts-Based Reconstruction for Multi-Spectral Computed Tomography
Lukas Kiefer, Stefania Petra, Martin Storath +1
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 t…
