IREX V Homepage

IREX V: Guidance for Iris Image Collection is now available. It consists of three parts: 1) a poster, 2) a final report, and 3) a collection of instructional slides.

IREX V provides guidance material for the proper collection and handling of iris images. Previous evaluations (IREX II, IREX IIIIREX III: Supplemental Report) have found that iris recognition accuracy is highly dependent on the quality of the iris samples. IREX V outlines simple procedures for iris camera operators to follow to ensure that the images they collect are good quality.

The IREX V products may be distributed worldwide.
