Abstract
In a FLIR image sequence, a target may disappear permanently or may reappear after some frames and crucial information such as direction, position and size related to the target are lost. If the target reappears at a later frame, it may not be tracked again because the 3D orientation, size and location of the target might be changed. We have proposed two methods: FKT-DCCF and FKT-PDCCF. We have implemented several tests by using DCCF and PDCCF when a target reappears to field-of-view. At the end of those test results we compared the DCCF and PDCCF methods by looking the percentage of correctly identified targets. Test results using both mid-wave and long-wave FLIR sequences (M1415, L1805, L1702, L1920, L19NS, and L1915) are incorporated to verify the effectiveness of the proposed algorithm.
