Well, this as interesting question for me too. A high-level interface (like "ResultIterator") for getting best results at word level does not exist. You need to dive into the guts of Tesseract. I can't give a ready recipe for this, only I can give you some kind of a probable guiding thread:
- Look into Wordrec::cc_recog() - Look into Dict::DebugWordChoices() - Check Dict::best_choices_ member It'd be great if share your findings with the community when you complete your investigation.
