Iris biometry has been proposed as a sound measure of personal identification. The iris, however, can change in response to physiological processes, medications and disease states. To develop a system Of iris recognition that is reliable requires identifying both the features that may alter and those that are stable, and finding an accurate way of localising these. The major iris characteristics from a series of photographs from Caucasian subjects are described. Algorithms, that consider accuracy of localisation of pupil centre and periphery, are presented and discussed.
