PATTERN RECOGNITION SYSTEMS

摘要

In pattern recognition systems for determining and recognizing any normalized characters registered in a record medium by means of a character characteristic extractor, the presence and absence of two-dimensional intelligence signals contained within the normalized characters to be recognized is determined by the consecutive scanning of only a single array of light-sensitive elements, while the record medium travels relative to the characters. Multiple intelligence signals for each group of the character segments developing across the respective elements are combined together in a signal compression mode and then introduced into a pattern decoding matrix in order to extract the character characteristic or pattern based upon a combination of the compressed intelligence signals.
