Title: Hand-written character recognizing device based on fuzzy inference
Inventor: OMORI KENJI
IPC: G06K9/62
Filed: 1988-06-10
Abstract: PURPOSE:To enhance the degree of confidence of the recognition of a hand-written character by expressing the coefficients of frequencies up to second one by a fuzzy value after inputting the hand-written character as sequence of points data and Fourier- transforming it by a stroke unit, and performing fuzzy inference according to a production rule obtained from a reference pattern. CONSTITUTION:In a course in which a character is written by hand, a character input means 1 outputs the character as the sequence of points data corresponding to X- coordinate and Y-coordinate to an input data normalizing means 3 by a prescribed time intervals. A Fourier transforming means 4 performs the Fourier transformation corresponding to X, Y moving amount of the hand-written character normalized by the input data normalizing means 3 by the stroke unit, and intensifies the intensity of the frequency, and further, makes obtained Fourier series data be fuzzy by a fuzzing means 5 so that it can be handled as fuzzy hand-written character data. A recognized character output means 9 outputs the character whose degree of confidence is decided to be high by a fuzzy inferring means 8 as the reference character data corresponding to the input hand-written character. Thus, processing time required for the recognition of the hand-written character is shortened.
