用ORL人脸库进行测试，给出一幅图片可以指出他是40个人中的哪一个人的第几个人脸，这些要以界面的形式显示出来并配以文字说明（文字说明就是哪一个人的第几个人脸），测试用的图片在一个文件夹中，我可以通过界面选择要测试该文件夹中的哪个图片，选定之后程序可以显示出对应这个图片的相应的ORL中的人脸并显示这是第几个人的第几张脸，如果在人脸库中检测不到测试的图片（如测试的图片是一朵花什么的）的话也要有提示说这个图在ORL中不存在 -Using the ORL face　to test, give a picture that can be pointed out that he is 40 individuals in which a few people face, which should be displayed in the form of interface and accompanied by text descr iption (text that is what a person In a folder, I can choose through the interface to test the folder in which the picture, after the selection process can be displayed corresponding to the corresponding image ORL in the face And show that this is the first few people face, if the face　can not be detected in the test picture (such as the test picture is a flower or something), then there must also be prompted that the figure does not exist in the ORL
