Efficient space-time discretizations for tracking the boundaries of reachable sets
Janosch Rieger, Kyria Wawryk
The reachable sets of nonlinear control systems can in general only be numerically approximated, and are often very expensive to calculate. In this paper, we propose an algorithm t…

Restriction and interpolation operators for digital images and their boundaries
Janosch Rieger, Kyria Wawryk
The aim of this paper is to provide a coherent framework for transforming boundary pairs of digital images from one resolution to another without knowledge of the full images. It i…

Towards optimal space-time discretization for reachable sets of nonlinear control systems
Janosch Rieger, Kyria Wawryk
Reachable sets of nonlinear control systems can in general only be approximated numerically, and these approximations are typically very expensive to compute. In this paper, we exp…
