A system and method for detecting breaklock for correlation trackers. The inventive system includes a first circuit () for computing energy Ein a residual image, a second circuit () for computing energy Ein an input image, and a third circuit () for computing a residual metric Rbased on the residual image energy Escaled by the input image energy E. In the illustrative embodiment, the system further includes a fourth circuit () for comparing the residual metric Rto a threshold T, and a fifth circuit () for setting a breaklock signal based on the output of the fourth circuit ().
