Elastic image registration with exact mass preservation
Jarosław Wlazło, Robert Feßler, René Pinnau +2
We establish a new framework for image registration, which is based on linear elasticity and optimal mass transportation theory. We combine these two arguments in order to obtain a…
Approximate Controllability of Linearized Shape-Dependent Operators for Flow Problems
Christian Leithäuser, René Pinnau, Robert Feßler
We study the controllability of linearized shape-dependent operators for flow problems. The first operator is a mapping from the shape of the computational domain to the tangential…
A Numerical Approach to Shape Optimization with State Constraints
Christian Leithäuser, René Pinnau, Robert Feßler
We present a general numerical approach to shape optimization with state constraints for 2-dimensional geometries, without relaxing the constraints. To do this we reformulate the p…
