APPARATUSES AND METHODS FOR IRIS BASED BIOMETRIC RECOGNITION
First Claim
1. A method for iris based biometric recognition, comprising the steps of:
- (a) receiving a first image of a first image region within a field of view of an imaging apparatus;
(b) receiving a second image of a second image region within the field of view of the imaging apparatus;
(c) performing a first determination comprising determining whether image information extracted from the first image matches stored iris information corresponding to at least one iris; and
(d) responsive to the first determination rendering a non-match decision, performing a second determination comprising determining whether image information extracted from the second image matches the stored iris information.

Abstract
The invention provides apparatuses, methods and computer program products for obtaining and processing images of one or more features of a subject'"'"'s eye for biometric recognition. The invention comprises receiving a first image of a first image region within a field of view of an imaging apparatus and receiving a second image of a second image region within the field of view of the imaging apparatus. Thereafter it is determined whether image information extracted from the first image matches stored iris information corresponding to at least one iris. Responsive to the first determination rendering a non-match decision, performing a second determination comprising determining whether image information extracted from the second image matches the stored iris information.

8. A system for iris based biometric recognition, comprising:
-
at least one image sensor; and a processing device configured for; (a) receiving a first image of a first image region within a field of view of an imaging apparatus; (b) receiving a second image of a second image region within the field of view of the imaging apparatus; (c) performing a first determination comprising determining whether image information extracted from the first image matches stored iris information corresponding to at least one iris; and (d) responsive to the first determination rendering a non-match decision, performing a second determination comprising determining whether image information extracted from the second image matches the stored iris information.

9. A method for iris based biometric recognition, comprising the steps of:
-
(a) receiving an image from an image sensor of an imaging apparatus; (b) accumulating evidence in support of similarity and/or dissimilarity of the iris information from the image in step (a) in comparison with at least one stored iris template; and (c) repeating steps (a) and (b) until sufficient evidence is accumulated to support either a match decision or a non-match decision with reference to at least one stored iris template or until occurrence of a termination event.
