ABSTRACT:
A character recognition device comprises a memory for memorizing standard patterns, each given by fundamental vectors. A dynamic matching unit finds out a maximum of degrees of coincidence between an input character and line patterns derived from each of the standard patterns by varying the magnitudes of the vectors between predetermined minima and maxima and derives similarity measures defined by the maximum degrees of coincidence between the input character and the line patterns derived from the respective standard patterns and specific line patterns for which the maximum degrees of coincidence are found. A decision unit compares the similarity measures with one another, judges whether or not the input character has a feature predetermined for each of the standard patterns, and delivers a result of the recognition in response to results of the comparison and judgment.
