A DISTANCE IRIS RECOGNITION
First Claim
Patent Images
1. A method comprising:
- acquiring an image of an eye;
estimating a center of the pupil;
identifying a border of the pupil;
adjusting the center of the pupil; and
segmenting an iris from the border of the pupil to at least an outside border of the iris.

Abstract
A system for one dimensional segmentation of an iris of an eye into a map of the iris and classification of the map into unaffected areas and affected areas. Also, the system may provide for regular shape fitting of the areas for normalization and identifying the unaffected areas as symmetric segments. Further, the system may assign weights to the unaffected areas and the affected areas of the map of the iris and an enrolled map of an iris and their corresponding bins for matching purposes.
