  1. The technology of identification based on iris is researched in the article, the key point of the technology is the iris characteristic acquisition and recognition, therefore based on the iris image texture characteristic, using the wavelet transforms to get the characteristic of iris image, a new method named zero - crossing detection and secondary circle coding is used in the article

    本文研究的就是用進行身份識別的技術,該技術的關鍵是特徵提取和識別。基於圖像的紋理特徵,利用波變換來提取圖像的特徵,本文提出了基於波過零檢測的循二次編碼的方法。

    動脈
  3. 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 + +

    首先改進了預處理方法,實現了一種快速高效的質量評價演算法;設計了一種改進的兩步定位演算法,準確的定位了的內外邊界;利用坐標轉換和編碼的循移位實現了對圖像的配準;利用雙三次樣條函數擬合圖像背景,去除了非均勻光照對識別的影響;使用二分樹復數波方法增強了圖像的對比度;在識別演算法方面,本文設計了一種「基於波模極值點位置的識別演算法」 。
