Character Recognition in Image in asp.net

Question

I would like to take an image, and index the words in that image, let the user search the image and then display the image highlighting around keywords.

So, what I need is an OCR class that takes an image and that gives me a list of words with their coordinates? Possible?

Answer 1

You can use these projects

• Tessnet2 (a .NET 2.0 Open Source OCR assembly using Tesseract engine)

• Tesseract-ocr (An OCR Engine that was developed at HP Labs between 1985 and 1995... and now at Google)

Answer 2

You can do it with Microsoft Office Document Imaging 12.0 Type Library.
