Method for determining the displacement of luggage in order to scan a suspicious region in the luggage

摘要

A first X-ray picture (XRP) (1) fixes the position of a piece of luggage (POL). A second XRP (2) is taken of the same POL in a second position different from the first. The first and second XRPs are then each subjected to pre-processing (10,20). Geometrical rectification is carried out along with optical pre-processing of intensities. Different features are measured for each picture content.
