Abstract

A near real-time invariant multi-target tracking algorithm based on the fringe-adjusted joint transform correlator (FJTC) technique is proposed for forward looking infra-red (FLIR) image sequences. The proposed FJTC based tracking approach uses a modified synthetic discriminant function (SDF) concept together with an efficient camera motion compensation technique to accommodate the problem of target signature variation due to 3D distortions and noise. The proposed technique can track small objects comprising of only a few pixels and is capable of compensating the high ego-motion of the sensor. The robustness of the proposed technique is demonstrated with computer simulation performed on sequences of real life FLIR imagery taken from an airborne moving platform.
