If I have trained a LBPHFaceRecognizer for different faces and stored the result in separate xml files, is ist possible for LBPHFaceRecognizer to read the separate model files and combine them for prediction? When I look into the LBPHFaceRecognizer xml files, I see that the persons (labels) are stored separate anyway. So it should be possible to write a program that can combine these files into one. But it would be nicer if the LBPHFaceRecognizer could do it.
