In order to improve the accuracy of iris recognition further,this paper proposed an iris recognition method base on the maximal responding orientation of energy.Firstly,obtained the normalized iris images by preprocessing eye image,selected multiscale and multidirectional filter by the feature of iris texture,decomposed the normalized iris image through the filter.Se-condly,extracted and encoded the maximal responding orientation on the pixel point into a simple binary iris code,performed denosing at the same time. The last,measured the difference of tow iris code through weighted hashiymming distance and gave the recognition results.The experimental results demonstrate that the proposed method has the equal error rate of 0.1176% and the correct recognition rate of 99.997%. Compared with the classical methods, the proposed method has a higher accuracy.
