According to the announcement in this link (devon-technologies.com/scripts/wordpress/), DEVONThink Pro Office 2 will have a new and different OCR engine. I must confess I am a little bit uneasy with such news, as I have just bought DTPO because of its OCR capabilities.
So far, DTPO has used the Read IRIS OCR engine. I suppose DTPO uses the latest version of the Read IRIS OCR, which is Pro 11, but I am not sure if this information is correct. Results so far have been good: recognition of characters is precise, given the PDF text is well scanned. However, I noticed that the DTPO OCR engine is slower than the OmniPage engine found in Microsoft Office OneNote 2007 (for Windows).
However, it seems that DTPO will start using ABBYY OCR engine from now on. In ABBYY website (www.abbyy.com), I could see that Fine Reader Engine 8.0 is available for MacOS. The current version of ABBYY Fine Reader for Windows is 9.0, so there could be some difference between them.
Version Tracker (at this link: versiontracker.com/dyn/moreinfo/macosx/31508) announces the ABBYY OCR engine as being faster and more accurate than the IRIS engine.
I wonder, how do these two engines really compare? Which is faster? And which is more accurate? Which are the advantages and disadvantages of exchanging engines?
