Как загрузить Face и повернуть его, чтобы оно распознавало лица ⇐ C#

[Гость]

I've been trying to create a face recognition system. I managed to write the code to save faces as objects and store them in a folder. However, I'm now confused about how to make it automatically recognize faces when I turn on the webcam, and turns the label to the face file name. Since my code I believe were simple than the Internet, so it makes me more confused, I'm all ears to hear every single advice and comment, thank you, shall I change the whole code?

  private async Task StreamVideo2() {     var faceCasade = new CascadeClassifier("./detection/haarcascade_frontalface_default.xml");     var vc = new VideoCapture(0, Emgu.CV.VideoCapture.API.DShow);      // Get the list of saved face images      string folder = Path.Combine(Application.StartupPath, "TrainedFaces");      string[] savedImages = Directory.GetFiles(folder, "*.bmp");      while (streamVideo)     {         var frame = new Mat();         var frameGray = new Mat();         vc.Read(frame);         CvInvoke.CvtColor(frame, frameGray, Emgu.CV.CvEnum.ColorConversion.Bgr2Gray);         var faces = faceCasade.DetectMultiScale(frameGray, 1.3, 5);         if (faces != null && faces.Length > 0)         {             CvInvoke.Rectangle(frame, faces[0], new MCvScalar(0, 255, 0), 2); // --> MCvScalar EMGU STRUCTURE [ RETACLE GREEN ON FACE ]             // Crop             var faceRect = faces[0];             var croppedFace = new Mat(frame, faceRect);             // LABEL             string labelText = "Detected Face";             var font = new Emgu.CV.CvEnum.FontFace();             var fontScale = 0.8;             var fontThickness = 1;             var fontColor = new MCvScalar(0, 255, 0);              var textOrg = new System.Drawing.Point(faceRect.X, faceRect.Y - 10);              CvInvoke.PutText(frame, labelText, textOrg, font, fontScale, fontColor, fontThickness);             // ResizedCroppedFace             var resizedCroppedFace = new Mat();             var resizedSize = new System.Drawing.Size(184, 192); // Size to keep the croppedFace.             CvInvoke.Resize(croppedFace, resizedCroppedFace, resizedSize);             // Convert cropped face to black and white (grayscale)             var grayCroppedFace = new Mat();             CvInvoke.CvtColor(resizedCroppedFace, grayCroppedFace, Emgu.CV.CvEnum.ColorConversion.Bgr2Gray);             // Display the grayscale cropped face in pictureBox2             pictureBox2.Image = grayCroppedFace.ToBitmap();         }         else         {             pictureBox2.Image = null;         }         // TURN CAMERA TO IMG PICTURE BOX         var img = frame.ToBitmap();         pictureBox1.Image = img;         label1.Text = "Mat Size: " + frame.Width.ToString() + " X " + frame.Height.ToString();         if (CvInvoke.WaitKey(1) == 27)         {             break;         }         await Task.Delay(16);     } }     private void button1_Click(object sender, System.EventArgs e)  {      if (pictureBox2.Image != null)       {                    string folder = Path.Combine(Application.StartupPath, "TrainedFaces");          string filename = textBox1.Text.Trim();          string savePath = Path.Combine(folder, $"{filename}.bmp");          // Saved As An Object          using var bitmapImage = new Bitmap(pictureBox2.Image);          bitmapImage.Save(savePath, System.Drawing.Imaging.ImageFormat.Bmp);          MessageBox.Show("Succed");          textBox1.Clear();                    if (!Directory.Exists(folder))          {              MessageBox.Show("Not Found");          }      } else      {          MessageBox.Show("Turn On The Camera");      }  }``` I tried few things, but it just make me lost more & more.
