Persistence Concepts for 2D Skeleton Evolution Analysis

In Topological Methods in Data Analysis and Visualization V, Springer International Publishing, pp. 139–154, 2020.


In this work, we present concepts for the analysis of the evolution of two-dimensional skeletons. By introducing novel persistence concepts, we are able to reduce typical temporal incoherence, and provide insight in skeleton dynamics. We exemplify our approach by means of a simulation of viscous fingering—a highly dynamic process whose analysis is a hot topic in porous media research.
