Hello everybody! I Am working on my masters degree. My first task is to do bananadetector by following this tutorial:

http://technobium.com/object-detection-with-opencv/ Did whole tutorial but in the end, detector doesn't work. It shows red rectangle saying "banana" in the wrong places, it doesn't recognize bananas. Total disaster. I have been trying to make it work for more than 10 days, but nothing helped. For training I made 1400 positives and 3000 negatives and used next commands to train model:

opencv_createsamples -info positives.txt -num 1200 -w 60 -h 80 -vec training.vec

opencv_traincascade -data data -vec training.vec -bg negatives.txt -numPos 1000 -numNeg 1000 -numStages 10 -nsplits 2 -w 60 -h 80 -featureType LBP -minhitrate 0.999 -maxfalsealarm 0.5

I have 3 more days to solve this till monday.

PLEASE, any help I am literally begging..

    std::vector<Rect> brezels;

    brezelDetector.detectMultiScale(frame, brezels, 1.1, 30,
            0 | CV_HAAR_SCALE_IMAGE, Size(200, 320));

    for (int i = 0; i < (int) brezels.size(); i++) {
        Point pt1(brezels[i].x, brezels[i].y);
        Point pt2(brezels[i].x + brezels[i].width,
                brezels[i].y + brezels[i].width);

        // Draw a rectangle around the detected brezel
        rectangle(frame, pt1, pt2, Scalar(0, 0, 255), 2);
        putText(frame, "Brezel", pt1, FONT_HERSHEY_PLAIN, 1.0,
                Scalar(255, 0, 0), 2.0);

    }

    // Show the transformed frame
    imshow("Brezel detecting camera", frame);

    // Read keystrokes, exit after ESC pressed
