Threat image projection HI-TIP
General
By means of HI-TIP, entire X-ray images of fictional baggage containing threat objects are automatically put between real baggage X-ray images during the inspection process. It is also possible to have single specific threat objects automatically projected into real X-ray images of scanned baggage.
The operator of the X-ray system is not aware of this projection process. While HI-TIP is active, the full range of image enhancement functions to support the evaluation process is available. Even automated operator support functions can be used in combination with HI-TIP. The task of the operator is to recognize and mark dangerous or suspect objects.

Operation
If a suspect object has been detected and marked by the operator, the conveyor automatically stops. The fictional threat object is now displayed with a black-and-yellow frame.
The fictional object disappears from the screen and the further evaluation of real screened baggage continues.

Check the bag to make sure ther are no real threats!
Missed objects
If the operator has missed an object projected on the image, the conveyor automatically stops and a message is displayed on the screen.
Real X-ray images and missed threat object images are automatically stored. These images can be recalled using the IMS Image Store System.

System configuration
The HI-TIP system provides a library divided into categories and subcategories containing combined, complete threat images and images of individual threat objects. The supervisor can add, edit and delete categories.
Moreover, users with supervisor access level can specify:
Moreover, users with supervisor access level can specify:
- from which categories and at which percentage in proportion to the other categories combined threat images and single threat objects are projected during the normal operational flow
- which images from a category are to be projected
- which decision times are provided for the operator to detect a threat image
- how many projections are made randomly rather than within the diversification range
- in what time the operator should detect a threat image
- the number of projections compared with the number of real bags
- the ratio between fictional projection and number of real bags
Reports
From the reports assigned to individual users, higher level users can interpret how many times projected objects and images were detected and how many of them were missed.
This is an advantage in rating the efficiency of security checks related to individual operators/users and in estimating personal workloads.
