Paper Abstract

Inspired by models of natural vision processing, intensity and color information are encoded and successfully decoded using coarse coding. Primate photoreceptors are known to include one rod and three cones, each with a unique spectral absorption curve. Although the curves overlap significantly, vision systems are capable of incredible chromatic acuity and spatial luminous acuity. A proof of concept is demonstrated here using simulated absorption curves and an algorithm representing a cursory model of vision processing. The color and intensity of objects within test images are successfully retrieved after passing through only two coarse filters arranged in a checkerboard fashion. A consequence of such a filter is a natural edge enhancement of the objects within the image.
