2015-11-06 02:01:44 -0600 | asked a question | Can find createFisherFaceRecognizer (opencv 3.0.0) I have successfully written an app that does face DETECTION Now I want to change it to do facial RECOGNITION. My current app has been written on my Mac for my Mac using CPP and xcode. After added the following line, I get the following error... FaceRecognizer faceRecognizer = cv::createFisherFaceRecognizer(0, 123.0); Unknown type name 'FaceRecognizer' I am guessing I am missing a .hpp file and or a dylib file. Can someone please tell me where this method is defined, and what .h files and libraries I should include? Rodger |
