Dynamic Cell Imaging in PET with Optimal Transport Regularization
Bernhard Schmitzer, Klaus P. Schäfers, Benedikt Wirth
We propose a novel dynamic image reconstruction method from PET listmode data that could be particularly suited to tracking single or small numbers of cells. In contrast to convent…
Image Labeling by Assignment
Freddie Åström, Stefania Petra, Bernhard Schmitzer +1
We introduce a novel geometric approach to the image labeling problem. Abstracting from specific labeling applications, a general objective function is defined on a manifold of sto…
Globally Optimal Joint Image Segmentation and Shape Matching Based on Wasserstein Modes
Bernhard Schmitzer, Christoph Schnörr
A functional for joint variational object segmentation and shape matching is developed. The formulation is based on optimal transport w.r.t. geometric distance and local feature si…
