中文摘要:采用基于PCA(主成分分析)的特征脸人脸识别方法,判断一张给定的图像是否为人脸图像。该方法通过计算训练集的特征向量,得到一个由特征脸组成的子空间,并将训练集中的人脸图像投影到该子空间中。检测人脸时,将二维的人脸图像投影到脸空间,并计算该图像与脸空间之间的欧几里得距离,以距离是否小于某一设定的阀值来识别是否人脸图像,实验测试结果准确率为97.5%。 |

Face Recognition Based on Principal Component Analysis with Eigenface |

Abstract:The main work of this thesis is to determine whether a given image is a human face picture by using the eigenface approach—a face recognition method based on PCA (Principal Component Analysis). The approach calculate eigenvector (or eigenface) from the training set to obtain a subspace spanned by the eigenfaces,and then project the face images in training set onto the subspace. When detecting faces,the two-dimensional face image is projected onto the face space and the Euclidian distance between the image and the subspace is computed. If the distance under a chosen threshold,then the image is classified as a face image,the accuracy of the test results is 97.5%. |
