Abstract:
1. A character recognition method for recognizing characters filled in a form having at least one character frame for filling a single character, comprising steps of: obtaining a characteristic vector of a character image in the character frame provided as an input signal; deciding the number of characters in one of the character frames using a discriminant function of the number of characters, wherein the discriminant function receives and discriminates using the characteristic vector extracted from the character image of the character frame and provides as an output a signal representing the number of characters contained in the frame; separating characters filled in the frame based on the output of the discriminant function; and recognizing the character thus separated using the characteristic vectors, obtained in the obtaining step, prepared for characters in a dictionary, wherein the discriminant function of the number of characters is a n-character discriminant function providing as its output a first function value for the input characteristic vectors each representing n (an integer not less than 1) number of characters filled in each character frame and providing as its output a second function value for the input characteristic vectors each representing other than n number of characters filled in the character frame.
