Abstract

This document provides guidance for the proper collection of iris images. Problems that occur during image acquisition can lead to poor quality samples. If the subject was looking down or blinking at the moment of capture, the image should be rejected and a new one acquired. Such problems are fairly simple and straightforward to correct, but require attentiveness on the part of the camera operator. If an image of a closed eye is accepted without scrutiny, no amount of post-capture processing can recover the lost information. For this reason, certain procedures should be followed to ensure only good quality samples are collected.
