Check out the info on the class at CS 4480 DVFX, Fall 08.

Abstract

We present propagation networks (P-nets), a novel approach for representing and recognizing sequential activities that include parallel streams of action. We represent each activity using partially ordered intervals. Each interval is restricted by both temporal and logical constraints, including information about its duration and its temporal relationship with other intervals. P-nets associate one node with each temporal interval. Each node is triggered according to a probability density function that depends on the state of its parent nodes. Each node also has an associated observation function that characterizes supporting perceptual evidence. To facilitate real-time analysis, we introduce a particle filter framework to explore the conditional state space. We modify the original condensation algorithm to more efficiently sample a discrete state space (D-condensation). Experiments in the domain of blood glucose monitor calibration demonstrate both the representational power of P-nets and the effectiveness of the D-condensation algorithm.

The DVFX Group at the Georgia Tech’s GVU Center and the School of Interactive Computing is aimed at exploring the technical aspects of digital video special effects production and computer animation. For more information see the research at the Computational Perception Laboratory, and the class offerings in this area since 1999.

Check out the New BS in Computational Media, and the BS in Computer Science and its related specialization tracks (threads!) as options for degrees that include material described here.
