| 摘 要： | 基于DiagPCA（对角主成分分析）及平均脸的方法对二维主成分分析（2DPCA）方法进行了改进,既考虑到构造2DPCA训练样本人脸间散布矩阵时使特征最大化,减少了同类人脸之间的特征差异,又利用图像矩阵对角化将图像的行、列关系联系起来,并利用ORL人脸数据库进行实验。结果显示,该方法可提高人脸识别率,且降低了特征提取的时间。

| Abstract: | Two-dimensional principal component analysis（2DPCA） method is one of the methods which are often used in face recognition.This paper has improved 2DPCA basing on the methods of average faces and diagonal 2DPCA,and this method does not only consider making features max when we tectonic the scatter matrix of training sample faces of 2DPCA,but also reduces the feature differences between the same-class faces,and connects rows and column of the image matrix by making the image matrix to diagonalization.And we did experiments on the ORL face database,it shows that this method has really improved the recognition. |
