ABSTRACT:
In an apparatus for identification of individuals, a facial image of an individual to be identified is inputted into a visual image input unit and characteristic points of the inputted facial image are extracted by a characteristics extracting unit. Characteristic points of expressionless facial images of individuals to be identified are stored in a data base. The difference between the characteristic points from the data base of individuals and the characteristic points from the inputted facial image is detected by a difference detecting unit. Further, the apparatus is equipped with a database of expression muscles wherein expression muscle movement vectors to form facial expressions are described. The apparatus is also equipped with an information processing unit whereby the difference information obtained from the difference detecting unit and the information as described in the data base of expression muscles are processed. By this processed information, coupled with the facial image inputted from the visual image input unit, the subject in question is identified.
