Kind Code:
B2
Abstract:
PURPOSE:To provide the method and device for recognizing a pattern with high discrimination accuracy by reducing mis-recognition rate for pattern discrimination. CONSTITUTION:A similarity calculation means 6 calculates a similarity L between a characteristic vector extracted by a characteristic extract means 2 and a characteristic vector associated by a characteristic association means 5 based on a correction category vector outputted from a discrimination means 3. A discrimination result discrimination means 4 discriminations a level of the calculated similarity L and the discrimination result outputted from the discrimination means 3 is outputted to be correct to an output means 7 only when a degree of similarity is high. Thus, the result of discrimination to an unknown pattern or a pattern onto which a high level noise is superimposed is aborted to reduce mis-recognition considerably.
