Abstract

PURPOSE: To realize pre-processing where strokes which should be separated originally are not connected, by connecting cut strokes by composing a recognition unit for a pattern such as a character of a separate-point detection circuit and circumference state detection circuit.
CONSTITUTION: When a signal of one-bit M in register 10 is "0", the output signal of separate-point detection circuit 20 "1", and that of circumference-state detection circuit 30 "1", the output signal of AND gate 40 is "1" and OR gate 50 outputs signal "1". Here, it is considered that point M given attention now is "0" and a stroke is cut there, buth this shows that the value of M is changed into "1" and cut parts are connected. If the output of circumference state detection circut 30 is "0" even when the value of M is "0" and the output of separate-point detection circuit 20 is "1", the output of AND gate 40 is "0" and that of OR gate 50 is also "0". Namely, a point given attention nor is separate point, but considered to be a point where strokes should be separated. showing that value "0" is maintained at it is.
