SIXray: A Large-Scale Security Inspection X-Ray Benchmark for Prohibited Item Discovery in Overlapping Images

Abstract: In this paper, we present a large-scale dataset and establish a baseline for prohibited item discovery in Security Inspection X-ray images. Our dataset, named SIXray, consists of 1,059,231 X-ray images, in which 6 classes of 8,929 prohibited items are manually annotated. It raises a brand new challenge of overlapping image data, meanwhile shares the same properties with existing datasets, including complex yet meaningless contexts and class imbalance.

“…In recent years, 2D X-ray image based threat object recognition has been extensively studied [1,2,24], although even the use of multiple view X-ray suffers from the challenges of object recognition under varying orientation and inter-object occlusion. This can be addressed by 3D X-ray CT imaging which provides abundant information as a 3D volume comprised of successive, parallel X-ray image slices [14].…”

“…Methods such as Faster R-CNN [11], R-FCN [18], and YOLOv2 [19], achieves maximal 0.885 and 0.974 mean Average Precision (mAP) over six-class object detection {Firearm, Firearm Component, Ceramic Knife, Laptop, Camera, Knife} and and two-class firearm detection {Firearm, Firearm Component} problems respectively. Here, we further investigate this performance with our evaluation on X-ray security imagery on larger dataset taken from different source, namely Durham University Full Two-Class and Security Inspection X-ray images [10]. Denoted as Dbf2 [9] and SIXray [10] respectively, it provide more inter-occluding Xray security imagery examples with large variations in pose, scale and item construction.…”
