Patent ID: 7660457

Claim:
A method, comprising: receiving from a first examination system a first image representing a position of an item of luggage in the first examination system; receiving from the first examination system a first list of coordinates of the first image that define a first suspect region in the item of luggage; taking, by a second examination system, a second image representing a position of the item of luggage in the second examination system; comparing the first and second images; determining a change in a position of the item of luggage in the second image relative to the first image using a first angle of rotation about a vertical axis, a second angle of rotation about a horizontal axis, and a translation; determining a probability value for at least one of the first angle of rotation and the second angle of rotation; converting, based on the change in the position of the item of luggage, the first list of coordinates into a second list of coordinates of the second image that define a second suspect region in the item of luggage, wherein the second suspect region corresponds to the first suspect region in the item of luggage; and performing, using the second examination system, a targeted examination of the item of luggage only in an area thereof that corresponds to the coordinates of the second suspect region when the determined probability value(s) exceed a predetermined threshold.
