Abstract
A new approach is proposed for detection of suspicious objects in X-ray images for security assurance. The approach is based on using the statistical model of the image for detecting anomalies. The model is designed with the use of the "bag-of-words" with context definition of the word coordinates in the image in forming the statistical pattern. It is experimentally demonstrated that this approach ensures adequate approximation of the result of detection of suspicious objects by humans.
