Hi, Thanks is advance. I am stuck with one issue in Open CV. I am using Local Binary Patterns Histograms (LBPH) Algorithm and creating a face recognition iOS app. In that at the 1st time I am registering the user by detecting the face by using video camera of iPhone. After the I am trying to recognise with the same face in that it is taking but the unknown face also its taking. I want to get value as "No match found" if any unregistered unknown face tries to recognise.

I tried with the confidence and label both. In confidence I took the value less then 70 as a correct and grater as a wrong. But in this case the original registered image is also not recognising if its little far as the trained image. Please anyone help me on this....
