An approach to model-based dynamic object verification and identification u
sing video is proposed. From image sequences containing the moving object,
we compute its motion trajectory. Then we estimate its three-dimensional (3
-D) pose at each time step, Pose estimation is formulated as a search probl
em, with the search space constrained by the motion trajectory information
of the moving object and assumptions about the scene structure. A generaliz
ed Hausdorff metric, which is more robust to noise and allows a confidence
interpretation, is suggested for the matching procedure used for pose estim
ation as well as the identification and verification problem. The pose evol
ution curves are used to assist in the acceptance or rejection of an object
hypothesis. The models are acquired from real image sequences of the objec
ts, Edge maps are extracted and used for matching, Results are presented fo
r both infrared and optical sequences containing moving objects involved in
complex motions.
