Open source preferred, but not necessary.
I've got Adobe Acrobat 8, and really like the OCR feature which can essentially put an invisible layer of OCR'd text on top of a scanned document. Thus what you see on screen is the original scanned document, but the result is searchable.
What I'm looking for is a way to automate this process. I've currently got a few scripts that we use for processing and archiving scanned files, and am looking for something that I can plug right in to this batch process to do OCR in a manner similar to what I can do with Acrobat.
All suggestions welcome, thanks!
