RECOGNITION UNIT FOR OPTICAL CHARACTER READING SYSTEM |
摘要 |
<p>RECOGNITION UNIT FOR OPTICAL CHARACTER READING SYSTEM A recognition unit accepts normalized character data from a multicell, single columnar retina across which a character image is scanned and converts the serial stream of digital character data into a parallel format for each scan and then correlates the data by comparing each cell with a composite of the surrounding cells to establish a black or white digital signal for each cell position. The signals are stored in a matrix array which is vertically analyzed to locate the character dependent cells. The character data is then shifted into a storage matrix and applied to a plurality of digital character masks for selection of the character represented by the data.</p> |
