Collaborative batch learning for crime scene detection
Surveillance camera is used in many settings to capture the real-life happenings. Lack of intelligent surveillance camera system decrease the effectiveness of surveillance camera in reducing crime. Our project developed a system to automatically detect crime scene event from the surveillance camera....
