  2. Due to the unique, stable and live physiological properties of the iris and non - invasive to users, most stable and reliable for identification in practical applications of iris - based system, iris recognition is receiving extensive attention and becoming an active topic in biometrics. as an application - oriented research project, iris recognition integrates mathematic, computer science, optics, electronics and physiology etc. based on wavelet transform, aimed to improve the recognition performance, centered at wavelet - based iris feature representation and pattern classification, we review and explore the iris sequence image quality assessment, iris image pre - processing, iris recognition performance evaluation and several other linked topics. we mainly investigate on the principles and application methodology of wavelet transform for iris feature representation and iris pattern classification methods

    以小波變換技術為基礎,結合圖像處理模式識別方法,設計並開發了虹膜圖像採集裝置,建立了虹膜識別演算法測試實驗平臺;重研究了虹膜識別中的小波變換的應用基礎理論與關鍵實現技術;提出了基於小波局部模極大值的虹膜特徵表示及其多重匹配識別、基於小波多尺度信息的一維二維虹膜紋理特徵化表示、基於小波過技術的虹膜特徵表示及其規范化的部分hausdorff離匹配識別,這三類方法能夠有效地提取虹膜特徵;基於自建的演算法測試平臺,對上述三類方法其他三種國內外比較有影響的基於小波變換的虹膜識別方法進行了定的性能比較評價,通過實驗數據分析得到了有意義的結論;最後指出了小波變換技術在虹膜識別領域的研究重與發展方向。
