Hi Tom, Thanks much for the update. I'm new to Ocropus, and I had a question on running rtrain.
Do you know (or have an estimate of) how many lines of text does the program take (to train) before it starts giving reasonable results? I'm wondering because since it's neural network based, I'd hazard a guess that it'd take more than a few thousand lines? More details: I'm working on gathering labeled data for Bengali (Bangla) OCR, and needed an estimate of lines that I'll need to transcribe as a starter.
