This document proposes a system to detect suspicious human activities in examination surveillance videos using a convolutional neural network model. It extracts optical flow features from video data and uses a 3D CNN for activity recognition. The system can recognize activities like object exchange, peering at answers, and person swapping. It detects these activities by recognizing faces, hands, and contact between hands and faces of different people. The model achieves better performance than other methods in detecting four abnormal behaviors from examination videos. It provides automated suspicious activity detection to help monitor examinations more accurately.
