This thrust focuses on multi-camera video anomaly detection in scenarios relevant to passenger tracking and area monitoring in public spaces. Signature analysis work will develop fundamental processing algorithms for trace; bulk and multi-sensor systems will extract maximal information from available sensed signals to increase the probability of detection and classification of explosives while reducing the number of false alarms. The research focuses on improved Model-Based Iterative Reconstruction for single and dual-energy X-ray CT, exploitation of new signatures such as multi-spectral CT and X-ray diffraction, threat detection in our novel trace sensors in Thrust R2, and algorithms for sensor fusion in AIT and standoff threat detection.
