At first we improve the methods of iris image preprocessing, including an efficient arithmetic of evaluation iris images, an improving method of locating iris, calibrating iris image by the translation of coordinate and the circular shift of code, a eatimate of the background illumination by bicubic spline, and the image enhancement by the dual tree complex wavelet transform. next we designed the recognition arithmetic based on the location of the local maxima of the wavelet transform modulus. in the thesis lots of simulation are performed by means of matlab and visual c + +
首先改進了虹膜預處理方法，實現了一種快速高效的虹膜質量評價演算法;設計了一種改進的兩步虹膜定位演算法，準確的定位了虹膜的內外邊界;利用坐標轉換和編碼的循環移位實現了對虹膜圖像的配準;利用雙三次樣條函數擬合虹膜圖像背景，去除了非均勻光照對虹膜識別的影響;使用二分樹復數小波方法增強了虹膜圖像的對比度;在識別演算法方面，本文設計了一種「基於小波模極值點位置的虹膜識別演算法」 。
