I'm trying to find a software and procedure to extract the lyrics and other text from printed sheet music. Capella-scan does a great part of it, storing it neatly in MusicXML for further processing. But I have not found a way to perform batch jobs for recognizing and converting OCR'ed text with Capella.
Do you know a command line interface to Capella, or other scanner software tools which are tightly integrated with quality OCR?
