Abstract:
Contrary to the other existing biometric technologies such as iris, hand geometry, fingerprint, voice, retinal, it is non-intrusive and can be used even without knowledge of the subject [3]. FR focuses on image processing and pattern recognition because of their wide range of applications, such as smart cards, criminal investigation, social network and access control [4]. Though FR has been considered for several years, it is still a challenging task due to the various types of large face variations, e.g., pose, expressions, illuminations, corruption, occlusion and disguises
