Я пытаюсь увеличивать и уменьшать каждый кадр из живого видеопотока с веб-камеры, открывая или прищурив глаза. У меня уже есть часть отслеживания глаз, но я не могу понять, куда вписаться в ScaleTransform. Ниже приведен существующий код, который у меня есть:

namespace eyeDetection
{
static class Program
{
/// <summary>

[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Run();
}
static void Run()
{
ImageViewer viewer = new ImageViewer(); //create an image viewer
Capture capture = new Capture(); //create a camera capture
Application.Idle += new EventHandler(delegate(object sender, EventArgs e)
{ // run this until application closed (close button click on image viewer)
Image<Bgr, Byte> image = capture.QueryFrame();
Image<Gray, Byte> gray = image.Convert<Gray, Byte>(); //Convert it to Grayscale
Stopwatch watch = Stopwatch.StartNew();
//normalizes brightness and increases contrast of the image
gray._EqualizeHist();
//Read the HaarCascade objects
HaarCascade eye = new HaarCascade("haarcascade_eye.xml");
MCvAvgComp[][] eyeDetected = gray.DetectHaarCascade(
eye,
1.1,
10,
Emgu.CV.CvEnum.HAAR_DETECTION_TYPE.DO_CANNY_PRUNING,
new Size(20, 20));
foreach (MCvAvgComp e in eyeDetected[0])
{
//draw the eyes detected in the 0th (gray) channel with blue color
image.Draw(e.rect, new Bgr(Color.Blue), 2);
}
watch.Stop();
//display the image
viewer.Image = image; //draw the image obtained from camera
});
viewer.ShowDialog(); //show the image viewer
}
}
