Claim 13:
14. A method for iris recognition, the method comprising:
acquiring, by an iris recognition device, at least two angularly differentiated iris images from a subject needing access, wherein the acquiring further includes:
acquiring, by an image capturing device in cooperation with a first illuminator, one of the at least two angularly differentiated iris images; and
acquiring, by the image capturing device in cooperation with a second illuminator, another of the at least two angularly differentiated iris images,
wherein the image capturing device, the first illuminator, and the second illuminator are spaced irrespective of redeye effects;

processing, by the iris recognition device, each of the at least two angularly differentiated iris images to generate at least one boundary delineated image from one of the at least two angularly differentiated iris images;
applying, by the iris recognition device, image comparative analysis to the at least two angularly differentiated iris images to generate a boundary delineated image when the processing fails to produce the at least one boundary delineated image;
segmenting and encoding, by the iris recognition device, one of the at least one boundary delineated image or 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.
