The anomaly in the crowd is a great potential threat, and the automatic detection of abnormal behavior for surveillance has become a hot topic in recent years. This report will give a brief introduction of several abnormal behavior detection methods, including intrusion detection, wandering detection and fence climbing detection. Experimental results show that by applying some efficient human detection algorithms, the anomaly can be detected in in time in surveillance videos, which shows certain research value. |
