SYSTEM AND METHOD FOR GENERATING AND EMPLOYING SHORT LENGTH IRIS CODES
First Claim
1. A computer readable storage medium comprising a computer readable program for generating compact iris representations based on a database of iris images, wherein the computer readable program when executed on a computer causes the computer to perform the steps of:
- computing genuine and imposter score distributions for full-length iris codes for iris images in a database, where the full-length iris codes include a plurality of portions corresponding to circumferential rings in an associated iris image;
identifying and retaining code portions that have a contribution that provides separation between imposter and genuine distributions relative to a threshold;
measuring a correlation between remaining code portions; and
generating a subset of the remaining code portions having low correlations within the subset to produce a compact iris representation.

Abstract
A system and method for generating compact iris representations based on a database of iris images includes providing full-length iris codes for iris images in a database, where the full-length iris code includes a plurality of portions corresponding to circumferential rings in an associated iris image. Genuine and imposter score distributions are computed for the full-length iris codes, and code portions are identified that have a contribution that provides separation between imposter and genuine distributions relative to a threshold. A correlation between remaining code portions is measured. A subset of code portions having low correlations within the subset is generated to produce a compact iris representation.

11. A system for generating compact iris representations based on a database of iris images comprising:
-
a database configured to store full-length iris codes for all iris images, where each iris code includes a plurality of portions corresponding to circumferential rings in an associated iris image; and a processor configured to compute genuine and imposter score distributions for the portions of iris codes and determine which code portions of the iris codes provide a highest contribution to a separation between imposter and genuine distributions, the processor being configured to measure a correlation between the remaining code portions to determine a subset of the code portions having lowest correlations within the subset such that a compact iris representation is generated from the subset. - View Dependent Claims (12, 13, 14, 15)
