The Efficient Display of Electro-Optical Imagery,
Abstract
Many remote systems require the use of electro-optical sensors and television displays. These systems require a wide bandwidth and a high ratio of picture element transmitted to picture element used. These two requirements exist because of inability of system designers to specify what information in a visual scene is important to the operator. A model of the human visual system (HVS) is used to identify prospective objects of interest in a visual scene. The approach is to use a coarse (peripheral vision) scan of the field of view, apply the HVS model to emphasize prospective objects, and apply a high-resolution (foveal) scan to each prospective object. The procedure was applied to a set of photographs in which 89% of the targets were detected using only 5% of the resolution elements required in a 512-line television system.
