此应用程序是利用特征法来识别人脸。假设你有一组人脸的数据库图像，首先你要计算出这些人脸的特征脸，然后输入一个需要检测人脸的图像，系统会从数据库中找出最接近的人脸。
This application is using the eigenface technologies for face recognition. Suppose you have a set of image faces, it will first calculate the eigenfaces. Recognition is performed by projecting a new face into a low-dimentional linear face space and then computing the distance with those of known eigenfaces. The best match will be output. In this package, we include 5 sets of face database image. After downloading the package, unzip it to a folder, then double click the run.bat. Select the training set directory and click the "Train" button, select testing set directory or single testing file and click the "Test" button.
