1. Get frame using Frame_GetCurrent() method. As alternative to process each video frame use OnVideoFrameBitmap event.
2. Process using any OCR library. 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;
}
