Abstract
This paper presents an innovative framework for real-time human action recognition in video surveillance systems, aimed at delivering immediate detection of suspicious behavior, normal movements, and actionable insights for security operators. The proposed method integrates computer vision and machine learning techniques to improve recognition accuracy and system reliability. Motion analysis is performed using optical flow, where Optical Flow Energy Images (OFEI) are generated to extract motion-related features. A Convolutional Neural Network (CNN) is utilized to obtain high-dimensional feature representations while reducing dimensionality, and a Support Vector Machine (SVM) classifier is trained on these features for robust action classification. The system effectively detects and distinguishes human actions such as walking, looking around, looking up, smashing, and suspicious activities, even under challenging conditions including camera motion, zoom-in, and zoom-out. Experimental evaluations conducted on publicly available human action datasets demonstrate significant improvements in recognition accuracy. Additionally, the system overlays detected actions onto video streams, providing clear and actionable visual feedback to surveillance personnel. Successfully deployed in intelligent video surveillance environments, the proposed framework proves to be scalable, accurate, and effective for identifying abnormal behaviors and generating timely alerts in modern security applications.
