二元模型 meaning in English

bigram

One of the immediate impacts of these discoveries was the conceptual difficulty inherent in adopting a dual model .
这一发现的直接影响之一是由二元模型固有的概念性困难所造成的。
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算法，指出算法中的不足，又结合数学形态学和hough变换等理论提出两种新的虹膜定位方法；虹膜特征提取算法中，研究了daugman对虹膜纹理的粗量化和编码，康浩等在daugman基础上的改进算法， muron等人的利用虹膜二元模型的傅立叶光谱分布特征进行识别以及boles的基于小波变换的虹膜识别算法等，比较出各个算法的优缺点，并且在boles的研究基础上进行了改进，经实验证明该方法可行。
