Some structural properties of functional map computation

11:00 - 11:30 KAUST

In recent years, several techniques have been proposed for computing and manipulating correspondences between shapes using the so-called functional map framework. Although capable of producing high quality results for problems such as shape matching and tangent vector field design, the exact structural properties, and in particular, the settings in which it can lead to point-to-point maps are not well understood. In this talk, I will give a brief overview of the basic ideas behind the functional map framework and then describe some recent work that allows to both incorporate and extract additional information from functional maps. Namely, I will discuss ways to characterize deformation fields as linear operators and a technique to use more information from a given set of descriptor constraints to obtain functional maps that follow structural properties of pointwise correspondences
