IRIS RECOGNITION SYSTEM AND METHOD
First Claim
1. A method for performing an identity search in a database of iris images for a probe iris image, comprising:
- generating a full-length iris code and a compact iris code for iris images in a database;
generating a full-length iris code and a compact iris code for a probe iris image;
scoring the compact iris code for the probe image against all compact iris codes in the database;
retaining a fraction of the database based on score data; and
scoring the full length iris code for the probe image against all the full length iris codes associated with the compact iris codes in the retained portion of the database.

Abstract
A system and method for performing an identity search in a database of iris images for a probe iris image includes generating a full-length iris code and a compact iris code for iris images in a database, and generating a full-length iris code and a compact iris code for a probe iris image. The compact iris code for the probe image is scored against all compact iris codes in the database. A fraction of the database is retained based on score data. The full length iris code for the probe image is scored against all the full length iris codes in the retained portion of the database.

17. A system for performing an identity search in a database of iris images for a probe iris image, comprising:
-
a database configured to store a full-length iris code gallery and a compact length iris code gallery; a scanner configured to obtain a full-length iris code for a probe iris image; a transform program configured to generate a compact iris code from the probe iris image; and a processing module configured to score the compact iris code for the probe image against all compact iris codes in the database, retain a fraction of the database based on score data, and score the full length iris code for the probe image against all the full length iris codes in the retained portion of the database to output best matches to determine an identify associated with the probe iris image. - View Dependent Claims (18, 19, 20, 21, 22, 23)
