AbstractDynamic Scene Analysis - a real time image registration, moving target detection, tracking, and geo-location software product. Registration is based upon Mutual Information, a more efficient and robust technique than traditional feature-based methods. Reference imagery and live imagery are utilized as needed to refine the estimate of the sensor position and attitude in the geo-registration solution. The algorithm automatically and adaptively performs the required computations to maintain the desired level of accuracy. Moving ground targets are automatically detected using an algorithm based on Optical Flow; it is ideally suited to separate object motion from perspective-generated scene motion, greatly reducing false alarms. Tracks are formed in geo-registered coordinates using an Associative Tracker, enabling tracking of irregularly moving or intermittently visible targets and fusion of target information from multiple sources. A process manager schedules images for processing based on the ancillary information taken along with the imagery and the processing resources available - thus, effective performance of the software is maintained even when processing power is reduced. The efficiency, flexibility, and adaptability of our processing stream lends well to implementation in a variety of computing environments. BENEFIT: This research will create a system that automatically detects, tracks, and geo-locates ground targets from airborne imagery for a wide variety of frame rates and image sizes. The processing is efficient and intended to be run on board the aircraft.
