Abstract
A character recognition system and method using the generalized Hough transform are disclosed. A template table which stores edge point parameters to be used for the generalized Hough transform is compressed so as to include only predetermined parameters, and is then divided into a plurality of template tables which are respectively loaded in the memories of a plurality of subprocessors operating in parallel under the control of a main processor. In performing recognition processing, these subprocessors operate in parallel according to their related partial template tables. Character recognition using the generalized Hough transform provides a high rate of character recognition. Also, parallel processing using the compressed template tables and partial template tables helps shorten table search time and computation time, thereby increasing processing efficiency.
