Abstract
Technologies are described for visualization of current and predicted crowd behavior information for surveillance. In surveillance systems, a variety of image capture devices and audio capture devices may be positioned strategically throughout a building or an area. The capture devices may transmit respective audio and video signals to a display device, such as a monitor in a surveillance control room, and to a signal processor for crowd behavior analysis. A signal processor, according to some examples, may receive crowd characteristics for an area, derive current crowd behavior information from the crowd characteristics, and predict crowd behavior information based on crowd characteristics, area characteristics, normalized crowd behavior information (from other areas), and/or external information. The signal processor may provide current and predicted crowd behavior information to a display device. The display device may overlay a corresponding video signal with a visualization of the current and predicted crowd behavior information.
