Analyzing video produced by a stationary surveillance camera.
Paolo Buono · 2011
Abstract — Today surveillance systems are every-where. Human observers watching live videos of specific areas are not efficient due to the likely loss of attention. On the other side, unattended surveillance systems re-quire that people analyze hours of recordings when they have to search for some specific events, e.g. identify peo-ple responsible of violence, theft or other offences. In many cases a specific search in the video has to be ac-complished in the shortest amount of time. This paper presents MotionFinder, a tool that performs video anal-ysis by computing an interactive summarization of the movements in a scene. Once the summarization process is complete, the tool responds in real time to inquires. For example, human investigators may search for spe-cific areas in the video that show high levels of activity or where they know that something occurred (e.g.: prop-erty damaged or stolen). The tool responds by showing only the scenes in which some activity occurred for that specific area of the video.
