- At present, the internet technology develops so rapidly and the video becomes the major component of the internet traffic. The content security of massive public videos is an important factor to the social stability. Among them, violent video is an important class of unsafe videos. We proposed a novel method based on dense trajectory and extreme learning machine to recognize them. The spatial-temporal characteristics were well expressed by the use of optical flow and gradient. The experiment on the benchmark dataset named Movies indicated our proposed method had a better accuracy than the state-of-the-art methods. Our proposed method is an efficient method for violent video classification.
