1. A method for facial recognition processing using biometric pre-filters, the method comprising: a computer identifying two eyes and a nose of a first detected face of a first image; the computer generating a first triangle, wherein the first triangle is a biometric measurement defined by points corresponding to a center of the first eye, a center of the second eye, and a nose-tip of the first detected face; the computer receiving a selection of a demographic characteristic; the computer determining a search range for the first triangle based, at least in part, on the selection of the demographic characteristic and the first triangle, wherein the determined search range includes a range of a length for at least one side of the first triangle; the computer identifying a second image from a plurality of images, wherein the second image includes a second detected face with a triangle formed by the eyes and nose of the second detected face that is included in the determined search range for the first triangle; the computer determining at least one potential identity that is associated with the first detected face based, at least in part, on an identity of the second face.
