1. A system for processing an image comprisinga generator for generating electronic signals representative of a digitized image, anda recognition engine for receiving the digitized image generated by said generator and for electronically converting information contained in said digitized image into symbolic form, anda memory for storing said information in symbolic form,said recognition engine including:

  • a first detector neural network comprising a plurality of detector nodes selectively interconnected only by forward feeding communication channels for receiving said digitized image produced by said generator as an input and for outputting an indication as to whether or not a particular optical pattern is present in said digitized image, anda second locator neural network comprising a plurality of locator nodes including one locator node corresponding to each detector node in said detector network, for receiving as an input the output of said detector network and for outputting an indication of the location of said optical pattern in said image.
