ABSTRACT
This chapter describes the results of several studies that performed to test the complementarity of information, obtained from different types of night vision systems. It examines the capability of several gray-level and color image fusion schemes to combine and convey information originating from different night vision imaging modalities, about both the global structure and the fine detail of scenes, for use in surveillance and navigation tasks performed by human observers. The chapter presents an experiment that was performed to test the effects of two gray-level and color image fusion schemes on the accuracy with which observers can localize a target while performing a military surveillance task. In the case of color vision in monkeys and man, retinal cone sensitivities are broad and overlapping, but the images are contrast enhanced within bands by spatial opponent-processing creating both on and off center-surround response channels.
