Oh boy, where to start! So first of all you are not alone not finding any information. Currently i am a week ahead of you, so im gonna share what i found out. Lets start with training_files.txt. Whats inside? /home/kh/tesstutorial/engtrain/eng.Arial.exp0.lstmf/home/kh/tesstutorial/engtrain/eng.Impact_Condensed.exp0.lstmf What is it for? it holds the location of .lstmf files, which are required for training (tesseract 4.*) How do i get it? if you manage to create starter training files it will create it with it so you dont have to write it on your own. Whats the difference between eval and train? as far as i know the only difference is their place in the training proccess. So i think you compare results from train training_files to eval training_files. (Sadly im still stuck on this question)
Thats all i know about these training files And for your second question: If thats possible i wanna know how. Currently for me it is a controversal question because there is no documentation and what you can find says that its not supported but others say oh you can do it (https://groups.google.com/forum/#!topic/tesseract-ocr/0r8QvV3j8ew) Hopefully i could help, currently im working on a newbie friendly documentation for tesseract 4.* training so if you get some info on topic, i would appreciate if you would send it. Good luck for going further into topic. 2019. február 4., hétfő 12:15:13 UTC+1 időpontban Krzysztof Kanafa a következőt írta: > > Helllo > > I'm completely new in tesseract, first version I'm using is 4.0.0.
