How to recognize unknown untrained image in Open CV
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....
Have you got any solution?
