ABSTRACT:
A system and method for detecting breaklock for correlation trackers. The inventive system includes a first circuit (50) for computing energy ELin a residual image, a second circuit (52) for computing energy EIin an input image, and a third circuit (54) for computing a residual metric RLbased on the residual image energy ELscaled by the input image energy EI. In the illustrative embodiment, the system further includes a fourth circuit (56) for comparing the residual metric RLto a threshold TR, and a fifth circuit (58) for setting a breaklock signal based on the output of the fourth circuit (56).
