加载EMGU自带的xml文件作为检测工具，难在参数的设置和调试

 static String face_cascade_name = Application.StartupPath + "\\Cascades\\lbpcascade_frontalface.xml";        static String eyes_cascade_name = Application.StartupPath + "\\Cascades\\haarcascade_eye_tree_eyeglasses.xml";        CascadeClassifier face_cascade = new CascadeClassifier(face_cascade_name);        CascadeClassifier eyes_cascade = new CascadeClassifier(eyes_cascade_name);        private void processfram(object sender, EventArgs arg)        {            Image<Bgr, byte> frame = new Image<Bgr, byte>("I:\\1.jpg").Resize(300, 400, Emgu.CV.CvEnum.INTER.CV_INTER_CUBIC);            Image<Gray, byte> grayF = frame.Convert<Gray, byte>();            //for (int a1 = 0; a1 < 20; a1++)            //{            //    for (int b = 0; b < 20; b++)            //    {            Rectangle[] faceArr = face_cascade.DetectMultiScale                (grayF, 1.1, 1, Size.Empty, Size.Empty);            Rectangle[] eyeArr = eyes_cascade.DetectMultiScale                (grayF, 1.1, 4, Size.Empty, Size.Empty);            //int falen = faceArr.Length;            //int eyelen = eyeArr.Length;            //if (falen * eyelen > 0)            //{            //    Console.WriteLine("A:"+a1+" B:"+b);            //    Console.WriteLine("FaceHarr:" + faceArr.Length);            //    Console.WriteLine("EyeHaar:" + eyeArr.Length);            //}            foreach (Rectangle detection in faceArr)            {                frame.Draw(detection, new Bgr(Color.Red), 2);            }            //if (eyeArr.Length == 2)            //{            //    foreach (Rectangle detection1 in eyeArr)            //    {            //        frame.Draw(detection1, new Bgr(Color.Blue), 2);            //    }            foreach (Rectangle detection in eyeArr)            {                frame.Draw(detection, new Bgr(Color.Blue), 2);            }            Console.WriteLine("FaceHarr:" + faceArr.Length);            Console.WriteLine("EyeHaar:" + eyeArr.Length);            pictureBox1.Image = frame.ToBitmap();        }

效果：
