Title: Intrinsic geometry for surface correspondence and symmetry analysis 
 
Abstract:
Finding correspondences between surfaces is one of the fundamental problems with applications in computer graphics, computer vision, paleontology and molecular biology. We leverage small dimensionality of certain intrinsic transformation spaces to efficiently explore isometric and near-isometric mappings between surfaces.
In the first part of my talk I will describe using "Moebius Transformations for Intrinsic Symmetry Analysis". The key idea is to explore a relatively small space of conformal maps to look for an intrinsic symmetry in a surface. In the second part of my talk I will concentrate on "Blended Intrinsic Maps" for inter-surface correspondence. In this work we propose a method for blending multiple intrinsic maps (with potentially large distortions for some parts) into a single map with low distortion everywhere.
