Abstract
A video tagging method, a video analytics method, and a Computer Assisted Dispatch (CAD) system use incident reports for video tagging and searching. A CAD system is integrated with field-based video surveillance systems to aid in searching video content and subsequent tagging of the video content. The systems and methods can include extracting keywords from a CAD incident report and creating a small, focused, and incident-specific dictionary on which to perform video searching in real-time. The small, focused, and incident-specific dictionary increases tagging accuracy and reduces tagging processing time in the context of video analytics. Further, a multi-pass approach in real-time continually updates and disseminates to video cameras of interest the small, focused, and incident-specific dictionary as the CAD incident report is updated and as the incident of interest plays out.
