Acxis – Automated Comparison of X-ray Images for Cargo Scanning

چکیده
The ongoing FP7 project “ACXIS Automated Comparison of X-ray Images for cargo Scanning” delivers enhanced inspection procedures for customs. A manufacturer independent reference data base for X-ray images of illegal and legitimate cargo is developed. One of the X-ray image recording work flow is to use 3D-CT data of illegal cargo mockups and to artificially generate arbitrary X-ray projections. By merging these X-ray projections and radiographic images of cargo freight containers with legitimate goods a high number of reference images can be obtained in a very efficient way. Based on these images an analysis system is developed consisting of image preprocessing methods as well as automated target recognition (ATR) algorithms supporting the inspection officer by identifying threat items automatically and highlighting them in the X-ray image.

Todays, X-ray imaging system for cargo and containers inspecting of country gates are highly regarded. The dual energy imaging system due to the use of two beams with different spectrums can extracts more information about the materials in cargo than the conventional X-ray imaging system. Since the X-ray beam is an ionizing radiation, three parameters should be taken into account including just...
متن کاملTackling the X-ray cargo inspection challenge using machine learning
The current infrastructure for non-intrusive inspection of cargo containers cannot accommodate exploding commerce volumes and increasingly stringent regulations. There is a pressing need to develop methods to automate parts of the inspection workflow, enabling expert operators to focus on a manageable number of high-risk images. To tackle this challenge, we developed a modular framework for aut...
متن کاملNano-structural Characterization of Post-annealed ZnO Thin Films by X-ray Diffraction and Field Emission Scanning Electron Microscopy
ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...

متن کاملAutomated X-ray Image Analysis for Cargo Security: Critical Review and Future Promise
We review the relatively immature field of automated image analysis for X-ray cargo imagery. There is increasing demand for automated analysis methods that can assist in the inspection and selection of containers, due to the ever-growing volumes of traded cargo and the increasing concerns that customs- and security-related threats are being smuggled across borders by organised crime and terrori...
