That is great. I am not a programmer and anything like this I have to spend lots of time to understand (if so). Sometimes I have to give up. So your generous help is highly appreciated.
Regards of the dataset, I think, it will not be possible for me, as in the site, for which you sent the link, they talk of several days even on an advanced machine. And lots of contributions of handwritten text.
Perhaps one day any institute will concern to do this tedious (and for me not possible) work.
Well, I am grateful, for what you offer and it is already a lot for me to play with . I am always interested in any forthcoming. Thank you very much again.
