Abstract :
We present an optimal Bayesian algorithm for integrated, multiframe detection and tracking of dim targets that move randomly in spatially correlated, cluttered image sequences. The algorithm consists of a multiframe minimum probability of error Bayes detector integrated with a multiframe maximum a posteriori (MAP) position estimator. The design of the detector/tracker incorporates the models for target signature, target motion, and clutter; it uses recursive spatio-temporal processing across all available frames to make detection decisions and to generate position estimates. A simulation with an artificial target template added to a real clutter background shows that the proposed algorithm outperforms the association of a standard single frame image correlator and a linearized Kalman-Bucy filter in a scenario of heavy clutter
