Abstract

Character and symbol encoding techniques are valuable in document processing systems for two reasons: (1) OCR makes available to standard typewriters the processing power otherwise accessible only through magnetic media (tape cassettes or cards). (2) The encoding techniques can represent the document image data very efficiently. For example, a 4000-character page may be represented by 20M bits of raw imaginal data, 1M bit of compressed data or as little as 32K bits of character codes plus some format overhead.
