Violence detection using Oriented VIolent Flows

Yuan Gao, Hong Liu, Xiaohu Sun, Can Wang, Yi Liu

Abstract: A novel feature named OViF for violence detection.•OViF makes full use of the orientation information of optical flows compared to ViF.•We use AdaBoost as a feature selector and Linear SVM as a classifier.•Experiments show that ViF + OViF obtain the state-of-the-art violence detection performance when using AdaBoost with SVM.
