Abstract

Many real-world actions occur often in crowded and dynamic environments. Video surveillance application uses crowd analysis for automatic detection of anomalies and alarms. In this position paper we propose a crowd event detection technique based on optical flow high-frequency feature analysis to build a robust and stable descriptor. The proposed system is designed to be used in surveillance videos to automatic violence acts detection. Preliminary results show that the proposed methodology is able to perform the detection process with success and allows the development of an efficient recognition stage in further works.
