Abstract

A system and method is disclosed for comparing biometric image data to a stored enrollment template that may comprise collecting a set of biometric image data for a biometric object image from a biometric object imaging sensor; storing the biometric object image data in a memory as an enrollment template for further comparison to find a match with subsequently imaged biometric object image data; collecting a subsequent set of biometric image data for a biometric object image from the biometric object imaging sensor; updating the enrollment template; determining if a limited enrollment window remains open; and repeating the collecting of a subsequent set of biometric data step if the enrollment window remains open. Determining if the enrollment window remains open may be by determining the existence of one of a stability indicator and an instability indicator.

First claim

What is claimed is:

1. A method comprising:
collecting a set of biometric object image data for a biometric object image from a biometric object imaging sensor during an initial enrollment window;
storing the biometric object image data in a memory as a stored enrollment template for further comparison to find a match with subsequently imaged biometric object image data;
collecting a subsequent set of biometric object image data for a biometric object image from the biometric…
