Our world is filled with nonrigid objects that can deform and bend. Nonrigid shapes appear at all scales - from our body, its organs and tissues, to tiny bacteria and microscopic protein molecules. When trying to analyze nonrigid shapes the richness of the possible deformations poses a challenge due to the large number of degrees of freedom. Thus, generally speaking, explicit analysis of nonrigid objects has so far been avoided. Today, there is a comprehension that in many applications the necessity to model and understand nonrigid objects is unavoidable. At the same time, recent research results demonstrate that there are feasible solutions to problems dealing with nonrigid shapes.

In this talk we give an introduction to analysis methods for nonrigid objects. We show how to adopt measures from metric geometry, and apply them to practical shape analysis problems, specifically in biometry, and to some geometry processing problems in computer graphics.
