Image Analysis and Registration Methods for Cargo and vehicles X-Ray Imaging

Abstract : Our societies, faced with an unprecedented level of security threat since WWII, must provide fast and adaptable solutions to cope with a new kind of menace. Illicit trade also, oftencorrelated with criminal actions, is viewed as a defining stake by governments and agencies. Enforcement authorities are thus very demandingin terms of technological features, asthey explicitly aim at automating inspection processes. The main objective of our research is to develop assisting tools to detect weapons and narcotics for lawenforcement officers. In the present work, we intend to employ and customize both advanced classification and image registration techniques for irregularity detection in X-ray cargo screening scans. Rather than employing machine-learning recognition techniques, our methods prove to be very efficient while targeting a very diverse type of threats from which no specific features can be extracted. Moreover, the proposed techniques significantly enhance the detection capabilities for law-enforcement officers, particularly in dense regions where both humans or trained learning models would probably fail. Our work reviews state-of-the art methods in terms of classification and image registration. Various numerical solutions are also explored. The proposed algorithms are tested on a very large number ofimages, showing their necessity and performances both visually and numerically.
