I tested the system on the ORL database (first 5 faces for training and the remaining ones for testing). I obtain 90% identification rate.
I tested the system on the AR database (segmented faces) (faces 1..3 for training and faces 7..9 for testing). I obtain 30% identification rate.
In my opinion this method is not recognizing the face. It is recognizing the shirt, hair, etc. If you remove this information, the method fails.
