Changing Views on Curves and Surfaces
Mathematisches Kolloquium

Referent: Prof. Dr. Bernd Sturmfels, Max-Planck-Institut für Mathematik in den Naturwissenschaften in Leipzig
Raum: S2|14 /24

Zuvor findet um 16:45 Uhr die Teerunde in Raum 244 des Mathematikgebäudes (S2/15), Schlossgartenstaße 7, statt.

This lecture explores visual events in computer vision. Given an algebraic curve or surface in 3-space, we consider the image or contour curve that arises by projecting from a viewpoint. Qualitative changes in that curve occur when the viewpoint crosses the visual event surface. We examine the various irreducible components of this surface, and show how to compute them using tools from algebraic geometry.
