C# and OCR

Question

How can I pass highlights image area to Microsoft Office Document Imaging (OCR) and get text output as a result? Or there is any alternative method to recognize the characters and numbers in image?

I know that this is an older post, however for those of you that come accross this post as I did, you can use the leadtools ocr sdk https://www.leadtools.com/help/leadtools/v20/dh/fo/iocrengine.html Here is some code showing how to use it: using (IOcrEngine engine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD, false)) { engine.Startup(null, null, null, null); string tifInput = @"INPUT FILE PATH"; string pdfOutput = @"OUTPUT FILE PATH"; using(IOcrDocument document = engine.DocumentManager.CreateDocument()) { IOcrPage ocrPage = document.Pages.AddPage(tifInput, null); orcPage.Recognize(null); document.Save(pdfOutput, DocumentFormat.Pdf, null); } ocrEngine.Shutdown(); }

The best program I have come across is the free trial of RE .NET OCR Recognition Library . Guess it may work for you C# application: OCR text from scanned, image-based document files & modify text and images within the scanned document files

Hey Prasad, There's a good article about using C# with MS Office OCR here: http://www.codeproject.com/Articles/41709/How-To-Use-Office-2007-OCR-Using-C However, if you need more control on selecting part of the image and getting only specific text out of it, you might need to use a commercial OCR toolkit, such as the one described here: http://www.codeproject.com/Articles/317163/OCR-with-LEADTOOLS-The-Better-Choice Cheers, Hjalmar
