GDXray: X-ray Images for X-ray Testing and Computer Vision

As a service to the X-ray testing and Computer Vision communities, we collected more than 21.100 X-ray images for the development, testing, and evaluation of image analysis and computer vision algorithms. The images are organized in this public database called GDXray+: The GRIMA X-ray database (GRIMA is the name of our Machine Intelligence Group at the Department of Computer Science of the Pontificia Universidad Catolica de Chile). The X-ray images included in GDXray+ can be used free of charge, for research and educational purposes only. Redistribution and commercial use is prohibited. Any researcher reporting results which use this database should acknowledge the GDXray+ database by citing:

GDXray includes five groups of images, they can be downloaded from the following links:

• Castings (314 MB)
• Welds ¹ (209 MB)
• Baggage (3.048 GB)
• Nature (192 MB)
• Settings (73 MB)

Each group has several series, and each series several X-ray images. For instance, series C0001 contains 72 X-ray images of an aluminum casting (wheel). See the mentioned paper for description.
