1. A method for iris recognition, the method comprising:
acquiring, by an iris recognition device, at least two differentially lighted iris images from a subject to be recognized, wherein a light intensity of a pupil area in each of the at least two differentially lighted iris images varies between the at least two differentially lighted iris images;
delineating, by the iris recognition device, an iris-pupil boundary by comparing a pupil area from one of the at least two differentially lighted iris images with another pupil area from another of the at least two differentially lighted iris images to generate a boundary delineated image;
segmenting and encoding, by the iris recognition device, the boundary delineated image to generate at least one iris template;
matching, by the iris recognition device, the at least one iris template against an enrolled iris; and
accepting, by the iris recognition device, the subject for access processing when the at least one iris template matches the enrolled iris.
