Model-based temporal object verification using video

Baoxin Li, R. Chellappa, Qinfen Zheng, S.Z. Der
2001 IEEE Transactions on Image Processing  
An approach to model-based dynamic object verification and identification using video is proposed. From image sequences containing the moving object, we compute its motion trajectory.  ...  The pose evolution curves are used to assist in the acceptance or rejection of an object hypothesis. The models are acquired from real image sequences of the objects.  ...  In the first experiment, simple verification is carried out on an infrared sequence acquired by a helicopter flying toward a tank.  ...
