Zusammenfassung:There is considerable rise in the research of iris recognition system over a period of time. Most of the researchers has been focused on the development of new iris pre-processing and recognition algorithms for good quail iris images. In this paper, iris recognition system using Haar wavelet packet, is presented. Wavelet Packet Transform which is extension of discrete wavelet transform has multi-resolution approach. In this, iris information is encoded based on energy of wavelet packets. The authors proposed work significantly decreases the error rate in recognition of noisy images. A comparison of this work with nonorthogonal Gabor wavelets method is done. Computational complexity of their work is also less as compared to Gabor wavelets method.
