Abstract:

        The widespread deployment of surveillance cameras, enabled by digital video technologies, has created an overwhelming volume of data that poses challenges for real-time analysis by humans. Automatic violence detection in surveillance videos has emerged as a crucial solution to address this issue. Leveraging the power of machine learning, this study explores the use of smart networks incorporating 3D convolutions to model dynamic relationships in video data, capturing both spatial and temporal aspects.

Through rigorous evaluation on diverse and challenging video datasets, our approach outperforms state-of-the-art methods, achieving a remarkable accuracy improvement with fewer model parameters. Furthermore, our experiments demonstrate the robustness of our method when confronted with common compression artifacts, making it suitable for remote server processing applications.

Introduction:

          Today, surveillance and security cameras are deployed in various public places to monitor public events and human activity. Video surveillance improves public safety and plays a crucial preventive role in protecting a specific territory against crimes. The recorded surveillance footage is often used as evidence in criminal prosecutions. To prevent crime and reduce the crime rate, detecting and recognizing anomalies such as violence as soon as possible is a crucial task for the military and law enforcement agencies. However, surveillance cameras generate a large amount of video data every single day and instances of violence occur very The associate editor coordinating the review of this manuscript and approving it rarely compared to other normal activities. Therefore, it is impractical and cumbersome for humans to manually monitor this video data for instances of violence. Human error may also reduce the efficiency of a manual, labour-intensive approach. Therefore there is a significant need for automatic and efficient methods for detecting abnormal or violent activities, especially in surveillance videos.
