Method of Material Recognition in Dual-Energy Security Inspection System
X-ray devices have demonstrated the ability to characterize a material at the molecular and atomic level. This ability is particularly important for detecting illicit materials. X-ray detection methods which have increasingly been an effective means for automatic detection of illicit materials is now commercially available,but most of these technologies are not yet mature. To classify different materials from the images by dual-energy X-ray transmission,the current method to calculate the eigenvalue R relating to effective atomic number is combining the highenergy transmission signal with low-energy one. Put forward a method based on R methods to get the features of material,and then find out the illicit materials.
