the program does not recognize objects

        static void Main(string[] args)
        {
            ProcessFrame();

        internal static String faceFileName = "cascade.xml";


        private static void ProcessFrame()
        {
            Image<Bgr, Byte> frame = new Image<Bgr, Byte>("006.jpg");
            CascadeClassifier face = new CascadeClassifier(faceFileName);
            Image<Gray, Byte> gray = frame.Convert<Gray, Byte>();


                Rectangle[] facesDetected2 = face.DetectMultiScale(
                        gray,
                        1.1,
                        4,
                        new Size(60, 60),
                        new Size(150,150));

                foreach (Rectangle f in facesDetected2)
                {
                    frame.Draw(f, new Bgr(Color.Blue), 2);
                }

            frame.Save("result.jpg");

        }
    }
}

the problem is that the program is not in a recognizable object on any of the images from a set positives

What am I doing wrong ?
