Best Open / Closed Source tool to do OCR

If you are running Win 7 or Server 2008 R2, the optional Windows component TIFF iFilter has OCR capabilities. I wrote my OCR option around that and it works really well. Best thing is, it is free if you are running one of these. You may want to investigate that as a possibility.

Hi Muthukumar,
This question is solved here -
C# OCR (How to Read a single character from image)[^]

Although Tesseract is one of the more accurate free OCR engines, the last time I tried it a couple of years ago it was rather inaccurate. After trying some other open source libraries, we faced similar problems with the other free OCR engines and winded up using leadtools that provided faster and more accurate results.

You can see an example in the following article:
Minimum OCR demo

There is no any solution which gives guarantee to read all JPG files as most of OCRs readers are based on preloaded font formats and at time of reading those JPG files must containing text in those supported font-families.

Otherwise all suggested solution provided by others should be used.

I have used few of them long back, and one problem you might faced is concatenation of text from Image where text are printed in various positions.

Thanks
