                 Physics-based Modeling Methods in 
             Vision, Graphics and Medical Image Analysis

We have been developing over the past 10 years a mathematically
rigorous and computationally efficient framework that has addressed
important problems in computer vision, computer graphics and medical
image analysis in a unified way. Most of these problems could not be
addressed successfully with traditional, non physics-based methods.

We will first present aspects of our work in computer vision and
medical image analysis related to the problems of shape from shading
and the analysis of the heart motion from MRI-SPAMM data.

In the second part of the talk we will present a new method for
modeling human walking that is based on a novel representation of the
saggital elevation angles. This method allows the real-time modeling
of human walking on both even and uneven terrain.
