  1. 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,去除了非均勻照對虹膜的影響;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演算法」 。
  2. Traditional laser iff has poor security because of low frequency of laser beam coded pulse. this can be greatly improved when the pulses are modulated by continuous wave laser, but the power of this laser beam output is so low that it ’ s difficult to be detected and received by laser warning subsystem

    傳統的激敵我器激脈沖頻率低,通信保密性差,使用連續波激器經調制后激脈沖頻率高,保密性好,但輸出激功率較低,難以達到激告警分機探測接收的要求。
  3. While in the feature extraction, four ways are researched such as the means of encode of iris texture, the improved algorithm based on daugman ' s, the approach of identification by means of the fourier spectra of the transmission binary model of the human irises and the method of iris identification using wavelet transform. the advantages and disadvantages of these ways are compared. improved algorithm based on wavelet transform is proposed and proves feasible

    虹膜定位中既分析了前人的一些演算法,指出演算法中的不足,又結合數學形態學和hough變換等理論提出兩種新的虹膜定位方法;虹膜特徵提取演算法中,研究了daugman對虹膜紋理的粗量化和,康浩等在daugman基礎上的改進演算法, muron等人的利用虹膜二元模型的傅立葉譜分佈特徵進行以及boles的基於小波變換的虹膜演算法等,比較出各個演算法的優缺點,並且在boles的研究基礎上進行了改進,經實驗證明該方法可行。
  4. Fractal neighbor distance gives a quantitative measure of the input - output characteristics of the fractal code of an encoded image. the fundamental mechanism behind this recognition scheme lies in the uniqueness of the attractor of a fractal code. the attractor has the invariance to image translation, rotation, scaling and illumination
