Title: Elastic Shape Analysis of Open Planar Curves

Speaker: Dan Robinson

Abstract:
An object's shape can be thought of as the geometric
information that is unchanged by transformations such as rigid motions,
uniform scaling, and reparametrization. Shape analysis deals with
developing precise mathematical descriptions of shapes, which can then
be used to quantify differences between shapes, define the notion of a
"most efficient" deformation of one shape into another, compute averages
of shapes, and perform many other tasks. In this talk, we will look
at a framework for shape analysis of open plane curves, in which one
curve can be deformed into another through a combination of bending and
stretching.
