ABSTRACT
The iris provides one of the most stable biometric signals for use in identification, with a distinctive texture that is formed before birth and remains constant throughout life unless there is an injury to the eye. The striations, filaments, and rings that make up the iris pattern are unique to each person, and the left eye differs from the right eye. Ophthalmologists first noted from clinical experience that every iris had a highly detailed and unique texture, which remained unchanged after the first year of human life. One of the major challenges of an iris recognition system is to capture a high-quality iris image while remaining noninvasive to the user. After the iris pattern has been analyzed, iris template generation extracts the unique iris patterns and stores them as a template that will be used for identification. When an iris image is presented for identification, an iris template is generated by the template generation algorithm.
