One-operation image algebra and optoelectronic cellular two-layer logic array

Abstract

A parallel binary image algebra with a logic operation followed by a dilation is developed in this paper. A cellular two-layer logic image processor architecture is proposed to execute such a one-operation image algebra, which consists of a parallel logic layer followed by a morphological layer. All the possible image processing functions can be written by the algebra. We construct an optoelectronic array based on optical logic operation using spatial coding techniques, optical neighborhood interconnection in a defocused system, and electronic thresholding and feedback. Any image transformation can be performed through iterative programming of the logic operations. Experimental results are also given.
