It can detect faces but after I assign names to them (Ex. Lucas, Carol, Paul)
It doesn't detect the person. I choose the try to recognize faces and got the
following output at the terminal:

 OpenCV Error: The function/feature is not implemented (This FaceRecognizer
(FaceRecognizer.LBPH) does not support updating, you have to use
FaceRecognizer::train to update it.) in update, file
/home/abuild/rpmbuild/BUILD/OpenCV-2.4.3/modules/contrib/src/facerec.cpp, line
305
