| 摘 要： | 对原始图像作对角变换,并在此基础上利用二维离散余弦变换(2DDCT)进行特征压缩,将人脸与虹膜特征相融合,利用二雏主元分析(2DPCA)分别从纵横双向进行特征提取,最后利用最小距离分类器进行识别.基于CAS-PEAL人脸数据库与CASIA虹膜数据库的实验结果表明,该方法降低了维数,有效地利用了分类特征信息,提高了正确识别率;证明了该算法的有效性,为多生物特征识别提供了一种新途径.

| Abstract: | Two-dimensional discrete cosine transform(2DDCT) is used in feature compression on the basis of image diagonal transform,and face and iris features are fused.Then 2DPCA is utilized in feature extraction from column and row direction respectively.Finally,nearest neighbor classifier is selected to perform recognition.Experimental results of CAS-PEAL face database and CASIA(Chinese Academy of Sciences,Institute of Automation) iris database show that the dimension is reduced,classified information is utilized ef-fectively,and the higher correct recognition rate is gained.In the meantime,the validity of the method is demonstrated,and a new approach is supplied for multimodal biometric identification. |
