This project is about analysing and classifying the fighting video from the UCF_Crimes dataset to explore solutions to detect fighting events employing computer vision technique. It is expected that different scenes need different approaches to solve the problems and innovative solution for each category should be implemented and tested. Anomaly detection is one of the most challenging tasks in computer vision due to ambiguous nature of the anomaly and the complex nature of human behaviours. Anomalous events rarely happen as compared to normal events which leads to the waste of labour and time. Motivation of this project is to detect a few categories of fighting events to timely signal such incidences as a warning and its innovation is to adapt the automatic anomaly detection and eliminate the use of manual anomaly detection.
