Video-rate Suspicious Object Detection for MMW Walk-through Imaging System

Near-range millimeter wave imaging techniques for persons have been widely used in public security field. To improve the throughput and security as well, a suspicious object detection method is designed for the Walk Through System we built. Simple Online and Realtime Tracking algorithm is applied based on the detection result of YOLOv5 in in each frame. The method can effectively detect objects at a video rate of 10Hz.
