In this paper, we introduce an efficacious way detecting abandoned object that is object that is deserted by any person. We carry out this detection process by using blob detection process, and foreground and background isolation. The system when experimented in real life scenario shows that the system successfully detects the abandoned object without any human intervention which surpasses the previous and existing methods. General Terms: Abandoned object detection, Short and long-term background isolation, Blob detection, Unmanned surveillance.
