Loading a saved yml file for LBPH Algorithm

edit

I've saved the model in .yml extension and tried to load it later. But unfortunately, I'm getting exception when loading the .yml file.

When I tried to recognize the face through predict function,

model->predict(preprocessedFace, identity, confidenceRatio);

it gives me the following exception:

Program has stopped working. 

Windows can check online for a solution bla bla bla...

So, someone please suggest how should I proceed to overcome the problem. Thanks.

My save code:

Ptr<FaceRecognizer> model;
cout << "Learning the collected faces using the [" << facerecAlgorithm << "] algorithm ..." << endl;

bool haveContribModule = initModule_contrib();
if (!haveContribModule) {
    cerr << "ERROR: The 'contrib' module is needed for FaceRecognizer but has not been loaded into OpenCV!" << endl;
    exit(1);
}

model = Algorithm::create<FaceRecognizer>(facerecAlgorithm);
if (model.empty()) {
    cerr << "ERROR: The FaceRecognizer algorithm [" << facerecAlgorithm << "] is not available in your version of OpenCV. Please update to OpenCV v2.4.1 or newer." << endl;
    exit(1);
}

model->train(preprocessedFaces, faceLabels);
model->save("lbph_trained_data1.yml");

My load code:

Ptr<FaceRecognizer> model;

cout << "Loading the file ..." << endl;

bool haveContribModule = initModule_contrib();
if (!haveContribModule) {
    cerr << "ERROR: The 'contrib' module is needed for FaceRecognizer but has not been loaded into OpenCV!" << endl;
    exit(1);
}

model = Algorithm::create<FaceRecognizer>("FaceRecognizer.LBPH");
if (model.empty()) {
    cerr << "ERROR: The FaceRecognizer algorithm [FaceRecognizer.LBPH] is not available in your version of OpenCV. Please update to OpenCV v2.4.1 or newer." << endl;
    exit(1);
}

model->load("H:\\Face\\lbph_trained_data1.yml");
cout << "file loaded successfully" << endl;
