Abstract

This article describes a system for pattern recognition made up of electronic logic elements which has many of the characteristics of humans for recognizing patterns. In particular, the recognition is invariant for size and will tolerate a specified amount of tilt or figure rotation. The electronic components or organs which make up this system consist of delay lines, logical elements such as “and” circuits, and photoreceptors.
