Iris identification using wavelet packets

We present a new method for iris identification particularly convenient for visible light images. It relies on the use of packets of wavelets (A. Laine and J. Fan, Nov. 1993) for the production of an iris code. Experiments, conducted on a database of 700 iris images, acquired with visible light illumination, show an improvement of 2% of FAR and of around 11.5% of FRR with the proposed method relatively to the classical wavelet method (J. Daugman, May 1995). The contribution of colour information is also studied with such method.
