Wavelet-Based Feature Extraction Algorithm for an Iris Recognition System

Free registration required

Executive Summary

The success of iris recognition depends mainly on two factors: image acquisition and an iris recognition algorithm. In this paper, the authors present a system that considers both factors and focuses on the latter. The proposed algorithm aims to find out the most efficient wavelet family and its coefficients for encoding the iris template of the experiment samples. The algorithm implemented in software performs segmentation, normalization, feature encoding, data storage, and matching. By using the Haar and Biorthogonal wavelet families at various levels feature encoding is performed by decomposing the normalized iris image.
