Abstract

Target detection models are an important means of evaluating military systems and tactics. The models currently in use within the United States rely solely on first-order statistical measures of targets and backgrounds. Using a series of computer-generated images, this paper demonstrates that such measures ignore perceptually important information having a significant impact on detection of targets by personnel using unaided eyes, direct view optics, or electro-optical devices. Second-order statistical measures are proposed as a means of improving model performance. The paper provides a brief synopsis of current research tying second-order statistical measures to target detection models.
