摘　　要：人脸识别是当今人脸图像处理领域的研究热点。为了得到良好的人脸识别效果,提出基于K-L变换和奇异值分解的人脸识别方法。首先采用K-L变换对人脸数据库中的人脸特征进行训练,以减少训练样本的规模,其次构建人脸训练数据库和测试数据库,最后采用欧式距离法选取距离最小的样本类别作为识别结果。实验结果表明,该方法人脸识别正确率较高。Face classification is a hot research issue in the field of face image processing.In order to get a good face recognition effect,a face recognition method based on K-L transform and singular value decomposition is proposed.Firstly,K-L transform is used to train the face features in the face database to reduce the size of training samples.Secondly,a face training database and a test database are constructed.Finally,the sample class with the smallest distance is selected as the recognition result used by Euclidean distance method.The experimental results show that the face recognition accuracy of this method is high.
