Technion CGGC seminar (talk #198) ============ Date: Sunday 27/01/2013 Time: 13:00 Room: Taub 337 Speaker: Maks Ovsjanikov (École Polytechnique, France) Title: Functional Maps: A Flexible Representation of Maps Between Shapes Abstract: This talk discuss a representation of maps between pairs of 3D shapes (represented as triangle meshes) that generalizes the standard notion of a map to include correspondences that are not necessarily point-to-point. This representation is compact, and yet allows for efficient inference (shape matching) and enables a number of applications, including algebraic map manipulation such as computing map sums and differences. The key aspect of this representation is that many constraints on a map, including landmark correspondences, part preservation and operator commutativity become linear. This means, in particular, that shape matching can be phrased as a simple linear system of equations. I will describe the main properties of this representation and give a few examples of applications that include improving existing correspondence, segmentation transfer without establishing point-to-point matches and efficient map compression and visualization. ------------------------------------------------------------------------ Visit the CGGC's web page at <http://www.cs.technion.ac.il/~cggc/> Seminar program: <http://www.cs.technion.ac.il/~cggc/Seminar/Seminar.html> --------------------------------------------------------- Technion Math.
