  Recent literature has witnessed significant interest towards 3D biometrics
employing monocular vision for robust authentication methods. Motivated by
this, in this work we seek to provide insight on recent development in the area
of 3D biometrics employing monocular vision. We present the similarity and
dissimilarity of 3D monocular biometrics and classical biometrics, listing the
strengths and challenges. Further, we provide an overview of recent techniques
in 3D biometrics with monocular vision, as well as application systems adopted
by the industry. Finally, we discuss open research problems in this area of
research
