Abstract:

X-ray images are widely used in security inspections. At present, most of the security inspections are done manually. However, the heavy workload and work intensity of X-ray security inspections make automatic security inspections an inevitable trend. Therefore, how to automatically detect objects based on X-ray images has become a research hotspot. With the great progress of object detection based on deep learning technology, deep learning models are also widely used in X-ray image prohibited item detection for research and obtain a lot of results. In order to summarize the existing research in a comprehensive and detailed manner, this paper first introduces the characteristics of X-ray images, the traditional methods of X-ray image detection and the methods based on deep learning, then compares the detection effects of traditional methods and deep learning methods, and analyzes the current research progress of automatic security inspection. Finally, in order to provide reference for the research of X-ray image prohibited item detection, this paper points out the research directions worthy of attention in the future.
