Iris recognition is depending on texture details of iris. At present, iris-encoding methods adopt wavelet transform mainly.Two-value iris template will be achieved by compare every point of convolve image with zero. At the stage of iris matching, making decision for test iris is depending on HD by comparing test iris template with template known. According to the criterion of matching, if the HD is smaller than classification, the tested iris can be regard as the known iris.
