Title: Functional Maps: A Flexible Representation of Maps (with 
Applications)

Abstract:
In this talk, I will discuss a representation of maps between pairs of 
3D shapes (represented as triangle meshes) that generalizes of 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.
