Abstract
The identity of an unknown character is determined by comparing matrices representing the unknown character with matrices representing known dictionary characters and determining the deviation between matrices for the unknown and the dictionary characters. By obtaining both matrices for the character and for the background surroundings of the character, it is possible to extract small differences between local portions of the character. The dictionary pattern of each character is automatically created by 'learning' and also the features of the character at the time of judgment and the related result are totalized so that the dictionary pattern can be created from the complementary cumulative matrices obtained by such totalization. By virtue of this advantage, it is possible to asymptotically improve the recognition rate.
