significant changes, such as shaving off a beard, can affect the accuracy of

image. For more information, see Register face image.

following situations may affect the results:

recommend that you to take off your glasses or wear colorless glasses with
very narrow rims. Be sunglasses or sport glasses.

in or out. Images taken by different video cameras might produce different
