An iris recognition system based on Wavelet Packet Analysis is described. The most unique phenotypic feature visible in a person's face is the detailed texture of each eye's iris. The visible texture of a person's iris is encoded into a compact sequence of 2-D wavelet packet coefficients, which generate an “iris code”. Two different iris codes are compared using exclusively OR comparisons. In this...
Iris recognition is one of effective methods for the biometrics recognition, while Empirical mode decomposition (EMD) is an effective technique for non-linear, non-stationary signal analysis. In this paper, an Iris recognition method based on an improved feature extraction approach is proposed, in which iris signal is decomposed into several Intrinsic Mode Functions (IMFs) by EMD first, and then one...
