Lip-prints feature extraction and recognition

Abstract

This paper proposes a method of personal recognition based on lip-prints. Biometric measures have been used to identify people based on feature vectors derived from their physiological/behavioral characteristics. One type of biometric systems used lip characteristics. Lip prints and lip shapes have many adventage for human identification and verification [1]. In this paper a texture lip features are extracted based on steerable filters and Radon transform. These features can be used in forensic applications and with other robust biometrics features (e.g. iris, fingerprints etc.) can combined multi modal biometric system. © 2011 Springer-Verlag Berlin Heidelberg.
