Abstract: The Hy-ALERT processing system operates simultaneously on the data streams from visible and thermal imaging sensors and from hyperspectral imaging sensors. The visible and thermal image processing uses cognitive-inspired processing techniques that determine the salient content of the imagers based on the system user definition of salient content. The hyperspectral image processing uses anomaly detection and template matching techniques to determine the salient materials content of the observed scenes. Cross-correlation processing of the salient content of the various image and hyperspectral data streams enables the sensor systems to adapt their operating characteristics to optimize effectiveness in near real-time.
