Matching two images

How can we match t开发者_如何学JAVAwo images using Java. I want to make a face recognition application, that will store face of people at some location and then later will check whether a person is a member or not. If the persons face will match a pic already in database, then the person will be authenticated else not. Is there a way to do so.

check this thread for java related face recognition software. You will need to use the Java Advanced Imaging library, which is a pain, but it's doable.

There is a way to do so. It is a well studied research problem. It is called face recognition in a gallery-probe setup. You should perhaps read this article.
