Color impact on security screening

Abstract

In order to improve aviation security, many airports
apply Threat Image Projection (TIP) and computer-based
X-ray image interpretation training (CBT). One
difference between TIP and CBT X-ray images is the
algorithm used to merge virtual threat items into X-ray
images of passenger bags, resulting in different color
nuances. In this study, we tested the influence of merging
algorithms on threat object detection performance,
reaction time and confidence rating of 12 airport security
screeners. The image merging algorithms of the
individually adaptive CBT X-Ray Tutor were used. We
have found that the hit rate was higher for TIP images
compared to CBT images. Accordingly, the mean of
confidence ratings was increased for TIP images. The
reaction times tended to be shorter for TIP images. The
results of our study indicate that the CBT merging
algorithm used in this study is more realistic than the
tested TIP image merging algorithm.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
