3D Tracking of Human Locomotion: A Tracking as Recognition Approach (ICPR 2002)

Tao Zhao


Estimating mode (walking/running/standi) and phases of human locomotion is impertant for video understanding. We present a new "tracking as recognition" approach. A hierarchical finite state machine constructed from 3D motion capture data serves as a prior motion model. Motion templates are used as the observation model. Robustness is achieved by making inferences in the prior motion model which resolves the short-term ambiguity of the observations that may cause a regular tracking formulation to fail. Experiments show very promising results on some difficult sequences.
