Abstract
A computing device prompts a user to place the user's hand next to a facial region of the user and obtains an image depicting the facial region and a finger of the user. The computing device measures a diameter of an iris in the facial region and measures a width of finger region located between two knuckles on the finger depicted in the image. The computing device estimates a ring size of the finger based on an actual iris diameter, the measured iris diameter, and/or the measured finger region width. The computing device outputs the estimated ring size.
