This paper presents a novel fall event detection method based on the motion vector and accumulated image map. The proposed method consists of the following steps; i) human object region extraction based on the background subtraction method, ii) generation energy map by accumulating the detected human object region during a consecutive time, iii) motion vector of human object obtained by optical flow...
Intelligent surveillance systems have become an important research issue recently. They can provide an early warning or help us to retrieve interested video frames. The motion detection techniques play an important role in these two applications. In this paper, we propose an effective surveillance video retrieval method based upon the motion detection technology. We can use this method to search frames...
