Dynamic Discrete Tomography
Andreas Alpers, Peter Gritzmann
We consider the problem of reconstructing the paths of a set of points over time, where, at each of a finite set of moments in time the current positions of points in space are onl…
Constrained clustering via diagrams: A unified theory and its applications to electoral district design
Andreas Brieden, Peter Gritzmann, Fabian Klemm
The paper develops a general framework for constrained clustering which is based on the close connection of geometric clustering and diagrams. Various new structural and algorithmi…
Reconstructing binary matrices under window constraints from their row and column sums
Andreas Alpers, Peter Gritzmann
The present paper deals with the discrete inverse problem of reconstructing binary matrices from their row and column sums under additional constraints on the number and pattern of…
On double-resolution imaging and discrete tomography
Andreas Alpers, Peter Gritzmann
Super-resolution imaging aims at improving the resolution of an image by enhancing it with other images or data that might have been acquired using different imaging techniques or…
