Anomaly Detection in Residential Video Surveillance on Edge Devices in IoT Framework

Intelligent resident surveillance is one of the most essential smart community services. The increasing demand for security needs surveillance systems to be able to detect anomalies in surveillance scenes. Employing high-capacity computational devices for intelligent surveillance in residential societies is costly and not feasible. Therefore, we propose anomaly detection for intelligent surveillance using CPU-only edge devices. A modular framework to capture object-level inferences and tracking is developed. To cope with partial occlusions, posture deformations, and complex scenes we employed feature encoding and trajectory associations. Elements of the anomaly detection framework are optimized to run on CPU-only edge devices with sufficient FPS. The experimental results indicate the proposed method is feasible and achieves satisfactory results in real-life scenarios.
