Patent ID: 7187786

Claim:
A method of verifying a face in a face verification system, comprising the steps of: (a) separating background and a face from an input face image to detect a face region; (b) detecting the positions of eyes from the detected face region and shifting the detected positions of eyes in predetermined directions by a predetermined distance, thereby generating new coordinate points of the eyes; (c) normalizing the face region on the basis of the new coordinate points of the eyes; (d) extracting recognition features from the normalized face regions and calculating feature values; (e) teaching a feature classifier using the feature values and storing the feature values in a database; (f) detecting a face region from another input face image for verification, normalizing the face region, extracting recognition features of a face, and calculating feature values; and (g) determining whether the input face image is similar to any face image registered in the database based on the feature values.
