Abstract: An apparatus for performing a security screening operation on receptacles to detect presence of one or more prohibited objects in the receptacles. The apparatus may comprise an input for receiving image data conveying an image of contents of a receptacle, the image data being derived from a device that scans the receptacle with penetrating radiation. The apparatus may also comprise a processing unit for determining whether the image depicts at least one prohibited object. The apparatus may also comprise a graphical user interface (GUI) for displaying a representation of the contents of the receptacle on a basis of the image data. The GUI may also display a representation of the contents of each of one or more receptacles previously screened by the apparatus. When a detection of depiction of at least one prohibited object is made, the GUI may display information conveying a level of confidence in the detection.

Abstract: An apparatus and method for implementing a user interface module for use in screening a receptacle to detect therein the presence of one or more prohibited objects is provided. An image signal associated with the receptacle conveying information related to the receptacle's contents and a detection signal conveying a presence of at least one prohibited object in the receptacle are received. A user interface module is adapted for displaying first information conveying an image associated with the receptacle on the basis of the image signal. The user interface module is also adapted for displaying, simultaneously with the first information, second information conveying the presence of the prohibited object in the receptacle. The second information is derived at least in part on the basis of the detection signal. As a variant, the user interface module is adapted for providing a control allowing a user to cause third information to be displayed.
