Incoherent Image Intensity Normalization, Contour Enhancement, and Pattern Recognition System.
Abstract
Incoherent optical processing techniques are shown which demonstrate image intensity normalization and contour enhancement. A new type of incoherent optical correlator which combines a model of the human neural system with an intensity image convoler. The processor's principal element is a Hughes liquid crystal light valve (LCLV). All components are commercially available and used without modification except for a liquid crystal television (LCTV). In operation the invention can be used as either a pre-processor to intensity normalize and edge enhance video scenes for use in pattern recognition applications or as a real-time pattern recognition device within itself, with the addition of an LCTV.
