Abstract:

Presenting observers with single frames of electronically gathered images of a scene denies the natural variability of signal and noise as they change across time. We discuss a methodology that preserves the temporal fluctuations of signal and noise thus faithfully representing the images produced by fielded hardware for use as laboratory perception study stimuli. Camouflaged military targets imaged by a 1st Generation Forward Looking Infrared FLIR system, were presented to observers in a simulated operational environment. Analog FLIR imagery from a Tube-launched Optically tracked Wire-guided TOW sight was digitized and looped to create a dynamic presentation. A test bed was designed to present the images and collect human performance data on a single desktop computer. The performance measures were time to detectionidentification and indication of the Visible Center of Mass of the targets. These data were scored using the Hit and Kill criteria from the appropriate military field manuals.
