Sample code

  1. Get frame using Frame_GetCurrent() method. As an alternative to process each video frame, use the OnVideoFrameBitmap event.
  2. Process using an OCR library. The best free library is Tessnet2.
private void VideoCapture1_OnVideoFrameBitmap(object sender, VideoFrameBitmapEventArgs e)
{
    Graphics grf = Graphics.FromImage(e.Frame);

    grf.DrawString("Hello!", new Font(FontFamily.GenericSansSerif, 20), new SolidBrush(Color.White), 20, 20);
    grf.Dispose();

    e.UpdateData = true;
}
