Abstract
The human being should remain the principal asset for the observation of the battlefield in the near future. An adequate evaluation of human detection performance, especially on Camouflage, Concealment and Deception (CCD) techniques, is of primary importance. This document represents an overview of the current laboratory methodologies for assessing the performance effectiveness of human observers in target acquisition tasks. The described evaluation methods, commonly called photosimulation or videosimulation, use field trial image sequences from photos or video tapes that are viewed by observers under controlled conditions. First, a brief review of the psychophysical processes involved in human visual search is discussed. Models of human behavior in image analysis elements are also given. Current metrics for the quantification of target acquisition processes and their potential sources of errors are presented. Recommendations are made for the design, conduct and data collection for photosimulation and videosimulation experiments. DREV's videosimulation facility, built around off-the-shelf image processing, videodisc and computer systems, is also described.
