MODELING HUMAN SEARCH AND TARGET ACQUISITION PERFORMANCE - FIXATION-POINT ANALYSIS

There has been an increase in attempts to quantitatively measure clutt er in the background of visual and infrared scenes; this parameter is crucial for determining the probability of detection of military targe ts in actual battlefield conditions. We analyze several clutter metric s by comparing the location of fixation points with the spatial distri bution of the areas of high clutter. We determine that a strong correl ation does exist.
