Abstract
Los Alamos National Laboratory's Safeguards Systems Group has developed an image-based digital video surveillance system designed to provide unattended and continuous monitoring of nuclear materials in storage or being processed. The MONITOR system was designed to reduce the frequency of physical inventories. MONITOR first collects a basis image representing the monitored scene and then continuously monitors the area to detect changes and record them in the form of difference images and supporting statistical data. These data show change in the monitored area. If no change has occurred, the data can be used to support extending the physical inventory period. When change is shown, the inventory can be focused directly on that object, providing a greater level of efficiency and effectiveness than is provided by current random sampling procedures.
