IFT patent “System and method for detecting and tracking multiple moving targets based on wide-area motion imagery” was granted. Threat detection of people, vehicles, and other (PVO) as well as person-vehicle interactions (e.g., dismounts) of possible malicious intent are difficult problems due to the complexity of the problem space. The challenges include cluttered scenes with obscured elements (e.g., buildings), varying camera sensor resolutions, different environmental conditions (e.g., illuminations), and unknown motivation of individuals. The patent is for method and system for detecting and tracking multiple moving targets based on wide-area motion imagery are provided.
