Hi
I want to try using Tesseract 4 for old manuscript languages ("The Song of
Roland" and such).
I have looked
at https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00
but the steps are very unclear.
I have an image and a text file with the line content for each line of
manuscript text. The doc says what to do, but not how.
I first thought I'd need img/box files pairs, but it seems it was for
Tesseract 3 and is now irrelevant...
So I guess my starting point is here
:
https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#tutorial-guide-to-lstmtraining
There is no tool to create the lstm-recoder directly. Instead there is a
> new tool, combine_lang_model which takes as input an input_unicharset and
> script_dir(script_dir points to the langdata directory) and optional word
> list files. It creates the lstm-recoder from the input_unicharset and
> creates all the dawgs, if wordlists are provided, putting everything
> together into a traineddata file.
I don't really get this part. How do I make input_unicharset ? What is
langdata?
Thanks
Guillaume Desforges
