Abstract
Optical correlation (OC) technology, previously used with great success to detect tanks and other weaponry in aerial imagery, is used in the present invention with imaged pages which are stored as image templates. An image template of a search word, a classification, an agency seal or a particular individual's signature becomes the basis of a user query. The target to be detected can be text as image (a search word, a classification) or image as image (an agency seal, a signature). The result is a faster (not one or two, but hundreds of times faster), flexible method of automatically identifying documents that match a target image template.
