ABSTRACT:
There is disclosed a character recognition method, and an apparatus therefor, capable of improving the accuracy of character recognition employing character normalization and direction index counting. The original image information is read with a resolving power matching the character size, so that the result of direction index counting is not distorted by the character size change in the normalization.
