Attached is a VS2017 C# project that uses the Leadtools Image processing and OCR SDK's in order to automate the process of checks. The Image processing command that is doing most of the work is the MICRCodeDetectionCommand:

Here is the relevant method for achieving this:

private string DetectandRecognizeMICR(string fileName)
            string micr = "";
            //Initialize the codecs class and load the image
            using (RasterCodecs codecs = new RasterCodecs())
               using (RasterImage img = codecs.Load(fileName))
                  //prepare the MICR detector command and run it
                  MICRCodeDetectionCommand micrDetector = new MICRCodeDetectionCommand();
                  micrDetector.SearchingZone = new LeadRect(0, 0, img.Width, img.Height);

                  //See if there is a MICR detected - if not return
                  if (micrDetector.MICRZone == LeadRect.Empty)
                     return "No MICR detected in this file.";

                  //if there is a MICR zone detected startup OCR
                  using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage, false))
                     ocrEngine.Startup(null, null, null, null);

                     //create the OCR Page
                     IOcrPage ocrPage = ocrEngine.CreatePage(img, OcrImageSharingMode.None);

                     //Create the OCR zone for the MICR and add to the Ocr Page and recognize
                     OcrZone micrZone = new OcrZone();
                     micrZone.Bounds = LogicalRectangle.FromRectangle(micrDetector.MICRZone);
                     micrZone.ZoneType = OcrZoneType.Micr;

                     //return the MICR text
                     micr = ocrPage.GetText(-1);
            return micr;
         catch (Exception ex)
            return ex.Message;

Please note that if you wish to make this into an automated process, you should not dispose of the OCREngine and should only start it up when the application/ thread is started and then shut it down/dispose of it once the application/thread is stopped.

Attached is the same project but modified to run using version 20 of the LEADTOOLS toolkit with the modified assembly names and the LEAD OCR engine (Which was renamed from the Advantage engine).
