Suspicious Activity Detection

Abstract

In light of the recent spike in anti-social behavior, security has been given top attention. Many firms have installed CCTVs to keep an eye on people and their interactions all the time. In a modern country of 64 million people, each person is photographed thirty times a day. A vast quantity of video data is generated and stored for a predetermined period of time. A picture taken at 25 frames per second at a resolution of 704x576 will generate over 20 gigabytes of data per day. Because it requires a workforce and their full attention, it is almost impossible for humans to continually monitor data to decide whether events are unusual. This implies that automation of the same is required.
