Colloquium - Saul

Machine-Learning Based Approaches to "Morphing"
AT&T Labs - Research
12/5/1996
3:45pm-4:45pm

Given a multidimensional data set and a model of its density, we consider how to define the optimal interpolation between two points. This is done by assigning a cost to each path through space, based on two competing goals -- one to interpolate through regions of high density, the other to minimize arc length. From this path functional, we derive the Euler-Lagrange equations for extremal motion; given two points, the desired interpolation is found by solving a boundary value problem. We show that this interpolation can be done efficiently and discuss applications to the "morphing" of facial images.

Refreshments will be served immediately before the talk at 3:30pm.
