“…Typical biometric technologies include face [ 1 , 2 ], fingerprint [ 3 , 4 ], iris [ 5 , 6 ], and finger-vein recognition [ 7 , 8 ]. In other studies [ 9 ], authors proposed 3D facial recognition based on 105 novel geometrical descriptors generated by composing primary geometrical descriptors such as mean, Gaussian, principal curvatures, shape index, curvedness, and the coefficients of the fundamental forms, and by applying standard functions such as sine, cosine, and logarithm to them.…”
