License Number read from an image in C#

You can use LEADTOOLS Recognition SDK technology in your application.

You can leverage the IOcrEngine interface, which will allow you OCR an image and output the recognized words.

Here is some sample code:

string inputImage = @"FILE PATH TO LICENSE PLATE IMAGE";
using (RasterCodecs _codecs = new RasterCodecs())
using (IOcrEngine _ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD))
using (RasterImage _image = _codecs.Load(inputImage))
{
// Startup the LEADTOOLS OCR Engine
_ocrEngine.Startup(null, null, null, null);
//Run the AutoRecognizeManager and specify PDF format
IOcrPage page = ocrEngine.CreatePage(viewer.Image, OcrImageSharingMode.None);
page.Recognize(null);
IOcrPageCharacters ocrPageCharacters = ocrPage.GetRecognizedCharacters();
ICollection words = ocrZoneCharacters.GetWords();
Console.WriteLine("Words:");
foreach (OcrWord word in words)
Console.WriteLine("Word: {0}, at {1}, characters index from {2} to {3}", word.Value, word.Bounds, word.FirstCharacterIndex, word.LastCharacterIndex);
}
