Visible, infrared IR and sensor-fused imagery of scenes that contain occluded camouflaged threats were compared for hit and miss differences in the probability of detection of objects. Response times were also measured. Image fusion was achieved using a Gaussian Laplacian pyramidal approach with wavelets for edge enhancement. Three types of images were also ranked in terms of better probability of detection of concealed weapons. Detecting potential threats that are camouflaged or difficult to see is important not only for military acquisition problems but, also for crowd surveillance as well as tactical use such as on border patrols. Imaging and display technologies that take advantage of photosimulation and sensor fusion are discussed in this paper.
