title: Howto: Improve the PDF- quality before OCR using C#
body: <p>I'm creating a service that monitors a folder for scanned files. Once the file is there, The service picks it up, and convert it to a readable PDF. In this process the service also searches for a barcode. After this, the text is extracted and the file, with its text is stored into the database of our software. The location is based on the barcode.</p>
  
  <p>Now, for the OCR we are using the SDK of Atalasoft (<a href="http://www.atalasoft.com/" rel="nofollow">http://www.atalasoft.com/</a>).
  Also the Barcode recognizer is included in this SDK.</p>
  
  <p>But the converted text still has some mistakes. (I ran some tests with other OCR-programs, but Atalasoft came out nice.) 
  I'm looking for some software (SDK-kit) which allows me to improve the quality of the PDF for OCR purposes.</p>
  
  <p>I tested Kofax VRS Elite (<a href="http://www.kofax.com/vrs-virtualrescan/" rel="nofollow">http://www.kofax.com/vrs-virtualrescan/</a>). I'm looking for something similar, but that can be implemented in the service using some kind of SDK-kit.</p>
  
  <p>Anyone who did this before, or had similar problems?
  thx in advance!</p>
