Which algorithm is used in iris recognition?
Finally, in the identification or verification stage, the hamming distance between IrisCode was calculated and hence attained the recognition result. Daugman's algorithm and workflow are still widely utilized in current iris recognition systems.
What are the main features of iris recognition?
Iris recognition systems take images of the eye using infrared light. Iris melanin is transparent under infrared illumination, this allows iris detail to be revealed regardless of eye colour.
What are the four steps for a iris recognition system?
The procedures for iris recognition usually consist of four stages: image acquisition, iris segmentation, feature extraction, and pattern matching. The iris recognition has been acknowledged as one of the most accurate biometric modalities because of its high recognition rate.
How is iris recognition done?
How Iris Recognition Works. Iris scanning measures the unique patterns in irises, the colored circles in people's eyes. Biometric iris recognition scanners work by illuminating the iris with invisible infrared light to pick up unique patterns that are not visible to the naked eye.
