【 摘 要 】

The biometrics are used to authenticate a person effectively compared to conventional methodsof identification. In this paper we propose the biometric algorithm based on fusion of DiscreteWavelet Transform(DWT) frequency components of enhanced iris image.The iris template isextracted from an eye image by considering horizontal pixels in an iris part.The iris templatecontrast is enhanced using Adaptive Histogram Equalization (AHE) and Histogram Equalization(HE).The DWT is applied on enhanced iris template.The features are formed by straight linefusion of low and high frequency coefficients of DWT.The Euclidian distance is used to comparefinal test features with database features. It is observed that the performance parameters arebetter in the case of proposed algorithm compared to existing algorithms.
