Learning-Based Object Identification and Segmentation Using Dual-Energy CT Images for Security
IEEE Transactions on Image Processing(2015)
摘要
In recent years, baggage screening at airports has included the use of dual-energy X-ray computed tomography (DECT), an advanced technology for nondestructive evaluation. The main challenge remains to reliably find and identify threat objects in the bag from DECT data. This task is particularly hard due to the wide variety of objects, the high clutter, and the presence of metal, which causes strea...
