Online face recogntion and tagging in opencv

edit

Hi,

I am following the code in this link for online face recognition. http://www.shervinemami.info/faceRecognition.html But I am facing a problem

1. I tried doing the training for many persons, one person at a time by giving a different name. But when I do testing, it displays same name for all people.

Can anyone help me?

Actually I want to tag known people in a video.(known people - whom i have trained)
