Re: [tesseract-ocr] How to created training text as provided in langdata for any new language if i have just just have a wordlist.

Just a word list is not enough for training text. For tesseract 4.0.0 it needs to be representative of the text to be recognized. On Sat 7 Apr, 2018, 2:50 PM Romil Mehla, wrote: > Is there any program to generate it ? i see ambiguous_words.cpp > generating dictionary words
