【Abstract】 Automatic fingerprint identification system is one of the important uses of biometrics,which refers to identifying an in-dividual based on his or her physiological or behavioral characteristics.Fingerprint enhancement can improve the clarity of the ridge structures of input fingerprint image,and ensure the performance of the minutiae extraction and fingerprint matching.Accord-ing to ant colony algorithm with clustering characteristics,a fingerprint image enhancement based on ant colony algorithm is pro-posed.This method can improve the quality for fingerprint image.更多还原
