Security and surveillance are the most important issues in today’s world. The recent acts of misconduct have highlighted the demand for efficient surveillance system. The recent surveillance systems use digital video recording cameras. The major disadvantage with this model is that it needs continuous manual monitoring which is in because of factors like human tiredness and cost of physical work. Moreover, it is virtually unfeasible to search through recordings for important events occur in the past since that it would need a playback of the complete duration of video footage. Hence, there is a requirement for an automated system for video surveillance which can detect unusual activities like physicalabuse (slapping, beating etc.) of people in real time environment and trigger an alarm to the pocket device of the concerned person.
