ABSTRACT:
An online handwritten character recognition system which performs the narrowing of candidates for handwritten character recognition quickly and very accurately by simple processing of a small amount of operations. A predetermined characteristic amount is extracted for each stroke, a characteristic amount word is created having a binary value of 1 only in one or more bit positions corresponding to selected values of the characteristic amount, an AND operation is performed bit-by-bit between the reference word of the corresponding stroke of the character of interest, and it is determined if all the bits of the results of the AND operation are zero. If the number of binary values of the results of the zero-determining operation for all the strokes of the character of interest exceeds a threshold, it is judged to be a candidate.
