This research combined image alignment techniques with techniques for processing neurophysiological signals to find consistent classifiers of changed and unchanged aerial reconnaissance images. These physiological markers were independent of explicit responses, and in fact, can compensate for errors made by analysts. In addition, we found that measures of eye movements have significant potential for use in image triage. This research has applications not only to the Intelligence community but also in commercial applications, such as analysis of medical imagery, geological and environmental studies, and building construction and inspection.
