This work shows an identification approach based on lip characteristics. For this proposal, the subject has to be without movement, with frontal face, without moving the lips by a neutral expression, angry or indifferent, therefore, not changing significantly the shape of the lips. After a preprocessing stage, global information from lips are extracted, reaching up to 9979%, using 5 training samples for the public RaFD database.
