Next Loria colloquium will take place on Thursday, 22nd May at 1:30 pm in the Amphitheater.
We will have the pleasure to welcome Bettina Speckmann, full professor at Eindhoven University of Technology, with a presentation in English, entitled River channels and dual loops: computational geometry in the field.
Abstract: Computational geometry is the area within algorithms research that deals with the design and analysis of algorithms and data structures for spatial data. In this talk I will present a variety of results which highlight the use of techniques from computational geometry and computational topology in two application areas: geomorphology and meshing. Specifically, I will first describe algorithms to extract meaningful networks from braided river systems and estuaries based on sediment volume and then show how to track these networks over time in the Western Scheldt and Wadden Sea. Secondly, I will present our latest results on creating valid polycube segmentations for 3D models of any genus.
