Violence Detection for Video Surveillance System Using Irregular Motion Information

Abstract

In this paper, we proposed violence detection method in surveillance video system. The proposed method consists of 4 steps: i) Detect the object region within a video image by background subtraction method and apply the morphology filter to reduce noise artifacts. ii) Estimate the motion vector using the Combined Local-Global approach with Total Variation (CLG-TV) in the object region. iii) Detect the violence event by analyzing the characteristic of motion vectors generated in the region of object by using the Motion Co-occurrence Feature (MCF).
