Abstract:

Research was performed to 1 identify the essential elements and pertinent parameters for a visual model for surveillance of camouflaged personnel in various terrains, weathers, and combat environments, and 2 develop the mathematics and logic of the visual model. A model was developed to account for the effects of luminance and color contrasts in the detection process. It accounts for intrinsic luminance and color contrasts at the target and the effects of the atmosphere and range between the observer and the object. The state of knowledge concerning the effects of movement and form discrimination was found to be fairly primitive despite the extensive research that has been performed. It was not possible to develop a sufficiently detailed analytical model for the effects of either of these important parameters. Since it is considered necessary to include a humans judgment in modeling the process of recognizing military objects, empirical data derived from human observers performance of form recognition, in conjunction with a classification system for backgrounds, are required for developing a realistic empirical model of form discrimination.
