Detection and Classification of Motion Boundaries

(Joint work with Allan Jepson, University of Toronto)


Given the trajectory of a moving object, what physically meaningful aspects of the motion can be recovered?

Consider the following trajectories of a single moving object.  Can you recognize the motion?


Here is the original video sequence.  Tracked object(s) are highlighed in the display.
