It's working now. I used the haarcascades_cuda instead of the normal one. I don't know why that worked if I'm not using the GPU but atleast it's working.

I tried it in c++ but I get the same result. What are the requirements for OpenCV? My laptop has a Intel and Nvidea gpu so maybe that's a problem.

Is the one on Github the latest?

The latest on github and the one included with 3.0.

The one on github was last updated 2 years ago, can you link me the new one?

Both are loaded when I check them, and without a face there are no eyes either. Check my edit.

I'm making the object detection tutorial in Java. The face detection is working but the eye detection crashes the program. Windows gives me a pop-up that says:

Display driver stopped responding and has succesfully recovered.

This is my code:

public Mat detectFace(Mat frame){
    CascadeClassifier face_cascade = new CascadeClassifier(face_cascade_name);
    CascadeClassifier eyes_cascade = new CascadeClassifier(eyes_cascade_name);

    Mat greyScale = new Mat();
    Imgproc.cvtColor(frame, greyScale, Imgproc.COLOR_BGR2GRAY);
    Imgproc.equalizeHist(greyScale, greyScale);

    MatOfRect faces = new MatOfRect();
    face_cascade.detectMultiScale(greyScale, faces);
    List<Rect> facesList = faces.toList();

    for(Rect face : facesList){
        Point center = new Point ( face.x + face.width*0.5, face.y + face.height*0.5 );
        Imgproc.ellipse( frame, center, new Size( face.width*0.5, face.height*0.5), 0.0, 0.0, 360.0, new Scalar( 255, 0, 255 ), 4, 8, 0 );

        Mat faceMat = new Mat(greyScale, face);

        MatOfRect eyes = new MatOfRect();
        eyes_cascade.detectMultiScale(faceMat, eyes);
        List<Rect> eyesList = eyes.toList();

        System.out.println(eyesList.size());

        for(Rect eye : eyesList){
            Point eyeCenter = new Point( face.x + eye.x + eye.width*0.5, face.y + eye.y + eye.height*0.5 );
               int radius = (int) ((eye.width + eye.height)*0.25 );
               Imgproc.circle( frame, center, radius, new Scalar( 255, 0, 0 ), 4, 8, 0 );
        }
    }

    return frame;
}

It crashes at eyes_cascade.detectMultiScale(faceMat, eyes) but face_cascade.detectMultiScale(greyScale, faces) works fine.

EDIT: It seems haarcascade_eye_tree_eyeglasses.xml is the problem. It doesn't crash when using another, but all the others I found don't detect the eyes. Does anyone have a working haarcascade?
