What is normalization of the iris?

One of the key stages in classical iris recog- nition is the normalization process, where the annular iris region is mapped to a dimensionless pseudo-polar coordi- nate system. This process results in a rectangular structure that can be used to compensate for differences in scale and variations in pupil size.

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.

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 is the process of iris scanning?

How it works. 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.
