Use of Periocular Biometric in Face Recognition

Biometrics is a technology to identify people based on their physical and behavioral traits. Enhancement in the field of biometrics have led to development of a trait that is non intrusive, widely acceptable and can be captured remotely with effective features. Face biometric is widely used trait all over world. Due to less efficiency of face biometric in non cooperative environment, researchers suggest to use a sub region of face that is more effective. Periocular biometric is region surrounding the eyes having modalities including eyebrows, eyelashes, eyelids, tear duct and skin texture. This paper explores use of periocular region and its modalities in face recognition including periocular databases and its use in future for various applications.
