Paper Abstract

Initial simulated optical correlation filter results to locate key words in destination address blocks on machine printed United States Postal Service (USPS) envelope mail are presented. The filters used are SDF MACE G-MACE and MINACE. These filters provide sharp correlation peaks allow controlled tolerance of intra-class (pitch font) variations and improved false class rejection (using symbolic filters).
