Elastic 3D-2D Image Registration
Paul Striewski, Benedikt Wirth
We propose a method to non-rigidly align a three-dimensional (3D) volumetric image with a two-dimensional (2D) planar image representing a projection of the deformed volume. The ap…
An adaptive finite element approach for lifted branched transport problems
Carolin Dirks, Benedikt Wirth
We consider so-called branched transport and variants thereof in two space dimensions. In these models one seeks an optimal transportation network for a given mass transportation t…
A mathematical model for cell polarization in zebrafish primordial germ cells
Carolin Dirks, Paul Striewski, Benedikt Wirth +3
Blebs are cell protrusions generated by local membrane-cortex detachments followed by expansion of the plasma membrane. Blebs are formed by some migrating cells, for example primor…
Consistent Curvature Approximation on Riemannian Shape Spaces
Alexander Effland, Behrend Heeren, Martin Rumpf +1
We describe how to approximate the Riemann curvature tensor as well as sectional curvatures on possibly infinite-dimensional shape spaces that can be thought of as Riemannian manif…
Green's function for Poisson's equation and the EEG equation with Neumann boundary condition on -balls
Benedikt Wirth
We provide an elementary derivation of the Green's function for Poisson's equation with Neumann boundary data on balls of arbitrary dimension, which was recently found in [Sadybeko…
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…
