Thank you, Marco. I will download the training tools packages and and
give it a try.
In future updates to the tesseract package, may I suggest packaging of
more languages from 'tessdata' - https://github.com/tesseract-ocr/tessdata
specially the ones which have multiple files for the language such as
ara, hin etc.
The languages that have just one file for traineddata can be downloaded
easily as a zip from the 'raw' link. It would be very helpful to have a
single tar/zip for the others.
all the languages data in tessdata are > 1GB
so I assume very few will need all,
and most will not appreciate a single file of
346M (compressed with xz )
May be a script to list/download/update from
https://github.com/tesseract-ocr/tessdata
will be more useful.
Question:
why tessdata includes other files than traineddata ?
$ ls -s1 rus*
1.0K rus.cube.fold
1.0K rus.cube.lm
892K rus.cube.nn
1.0K rus.cube.params
15M rus.cube.size
6.8M rus.cube.word-freq
16M rus.traineddata
From the wiki I had the impression that
traineddata should include all the others file inside.
Are all the files for a language needed or only the
{lang}.traineddata ?
Langdata includes a different set of files
$ ls -s1 rus*
total 22M
1.0K desired_characters
8.0K rus.cube-unicharset
1.3M rus.cube-word-dawg
4.0K rus.numbers
8.0K rus.punc
16K rus.training_text
96K rus.training_text.bigram_freqs
4.0K rus.training_text.unigram_freqs
8.0K rus.unicharambigs
11M rus.word.bigrams
11M rus.wordlist
There is a description of the different type of data ?
Marco
