Samples

Code

• Image devignetting:

  var image = ImageIO.LoadColor("(your image)").Clone();
  image.Devignette(optimizeVignettingCentre: true);
  image.Show("Corrected", scaleForm: true);

• Video devignetting:

  //initialize capture and buffer
  VideoCaptureBase capture = new FileCapture("(your video)"); // /*or*/ capture = new CameraCapture();
  Bgr<byte>[,] frame = null;

  //initialize devignetting alg
  capture.ReadTo(ref frame);
  var devignetting = new Devignetting(frame, optimizeVignettingCentre: true);

  //do the job
  while(true)
  {
      capture.ReadTo(ref frame);
      if (frame == null) break;
        
      devignetting.DevignetteSingleStep(frame);
      frame.Show("Corrected");
  }

  capture.Close();
