Abstract
Systems and methods pertaining to iris recognition are disclosed. A system is disclosed comprising an iris imager configured to acquire an iris image, and a processor configured to receive a first plurality of iris images from the iris imager, generate a first plurality of iris codes corresponding to the first plurality of iris images, generate a distribution metric corresponding to an iris cell location, generate a first composite iris code using the distribution metric, and generate a first match value using the first composite iris code and a first stored iris code.

A system comprising:
- an iris imager configured to output iris images of an eye having an iris, the iris associated with a first iris cell location and with a second iris cell location;
- and
- one or more processors configured to perform a method comprising:
- receiving a first iris image from the iris imager, the first iris image comprising a first iris cell corresponding to a first iris cell location;
- receiving a second iris image from the iris imager, the second iris image comprising a second iris cell corresponding to a second iris cell location different from the first iris cell location;
- generating a first composite iris code associated with the eye, the first composite iris code based on the first iris image and based further on the second iris image, the first composite iris code comprising a third iris cell corresponding to the first iris cell location and further comprising a fourth iris cell corresponding to the second iris cell location;
- comparing the first composite iris code and a first stored iris code;
- and
- generating a first iris match value based on the comparison,
- wherein generating the first composite iris code comprises:
- applying a first distribution metric to the first iris image to determine the third iris cell, and
- applying a second distribution metric to the second iris image to determine the fourth iris cell.
A method comprising:
- receiving a first iris image from an iris imager configured to output iris images of an eye having an iris, the iris associated with a first iris cell location and with a second iris cell location, the first iris image comprising a first iris cell corresponding to a first iris cell location;
- receiving a second iris image from the iris imager, the second iris image comprising a second iris cell corresponding to a second iris cell location different from the first iris cell location;
- generating a first composite iris code associated with the eye, the first composite iris code based on the first iris image and based further on the second iris image, the first composite iris code comprising a third iris cell corresponding to the first iris cell location and further comprising a fourth iris cell corresponding to the second iris cell location;
- comparing the first composite iris code and a first stored iris code;
- and
- generating a first iris match value based on the comparison,
- wherein generating the first composite iris code comprises:
- applying a first distribution metric to the first iris image to determine the third iris cell, and
- applying a second distribution metric to the second iris image to determine the fourth iris cell.
A non-transitory computer-readable medium comprising instructions which, when executed by one or more processors, cause the one or more processors to perform a method comprising:
- receiving a first iris image from an iris imager configured to output iris images of an eye having an iris, the iris associated with a first iris cell location and with a second iris cell location, the first iris image comprising a first iris cell corresponding to a first iris cell location;
- receiving a second iris image from the iris imager, the second iris image comprising a second iris cell corresponding to a second iris cell location different from the first iris cell location;
- generating a first composite iris code associated with the eye, the first composite iris code based on the first iris image and based further on the second iris image, the first composite iris code comprising a third iris cell corresponding to the first iris cell location and further comprising a fourth iris cell corresponding to the second iris cell location;
- comparing the first composite iris code and a first stored iris code;
- and
- generating a first iris match value based on the comparison,
- wherein generating the first composite iris code comprises:
- applying a first distribution metric to the first iris image to determine the third iris cell, and
- applying a second distribution metric to the second iris image to determine the fourth iris cell.
