VideoZoom: Summarizing surveillance images for safeguards video reviews
This report presents VideoZoom, a prototype review tool that builds automatic summaries out of sequences of surveillance images taken by cameras with a fixed point of view. These summary images are then visualised in a zooming user interface allowing the discovery and annotation of images of interest.
The prototype system was used for detection of safeguards-relevant events in image sequences acquired in nuclear facilities. A first evaluation of the prototype system with inspectors from DG-ENER was performed. Results indicate that the system allows accurate reviews, can save effort and is easy to learn and use. In addition the system allows detection of unexpected events which would be missed by standard review tools.
