[Retracted] X-Ray Small Target Security Inspection Based on TB-YOLOv5

Table 2

Performance comparison of different object detection algorithms. With the progression of YOLO detector, the performance becomes much better for newer version, and the different network structures show different detecting results for YOLOv5.
