Iris identification and robustness evaluation of a wavelet packets based algorithm

This paper presents an iris recognition system, based on a wavelet packet analysis using orthogonal wavelets. The identification of the different packets that carry discriminating information about the iris texture is carried out through an energy measure. Tests, conducted on a database of 149 high quality iris images show good robustness in relation to changes in illumination, blurring, optical axis deviation or local defects in the images.
