Abstract: Disclosed are systems, apparatus, devices, methods, computer program media and products, and other implementations, including a method that includes capturing an RGB image of a hand of a person, capturing a near infrared (NIR) image of the hand, and determining geometrical features of the hand based on the captured RGB and NIR images. In some embodiments, determining the geometrical features may include determining from extracted image data for the hand one or more values representative of relative spatial features for the hand such as one or more of, for example an angle between a first pair of two fingers in the extracted image data for the hand, and/or a relative distance or length for a second pair of fingers in the extracted image data for the hand. In some embodiments, the method may further include determining identity of the person based on the determined geometrical features of the hand.
