The visual inspection of x-ray images of luggage items at airports is a challenging task, where detection rates suffer when threat item complexity increases [1].The relationship between threat-item types, aspects of image difficulty, and decision time are explored using a combination of Drury's Two-Component Model [2] and Signal Detection Theory [3]. 67 professional screeners completed a 2048-image battery that manipulated various image-based difficulty factors. A strong linear relationship… CONTINUE READING
