Re: [tesseract-ocr] Error at training 4.0

2018-04-04 Thread ShreeDevi Kumar

Training tesseract 4.0.0 is different from process for 3.0x.

Training  using images is not supported for tesseract 4.0.0.

See https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00

[tesseract-ocr] Error at training 4.0

2018-04-04 Thread Fanatico

Hi, I'm new to tesseract and ocr in general, and need some help to train my 
tesseract.

Config
Platform: Mac OS X 10.13.3
Tesseract Version: 4.0.0-beta.1
leptonica: 1.75.3
  libjpeg 9c : libpng 1.6.34 : libtiff 4.0.9 : zlib 1.2.11

images used

kor.AppleMyungjo.exp1.tif




kor.AppleMyungjo.exp0.tif




Step by step
I'm trying to train (fine tuning) my tesseract to better detect commas (") 
and dot (.) in korean, but I'm getting some errors. Here what I did until 
now:

1 - Got the Images, I'm using 2 images .tif (both images has only 1 line 
and few characters)
2 - Renamed the images to kor.AppleMyungjo.exp0.tif and 
kor.AppleMyungjo.exp1.tif
3 - Created the .box file for each image ```tesseract 
[language].[fontname].exp[samplenumber].tif 
[language].[fontname].exp[samplenumber] -l [language] batch.nochop 
makebox``` (one of them come empty)
4 - Corrected the .box files using the site 
https://pp19dd.com/tesseract-ocr-chopper/ (I just pasted the positioning in 
the file)
5 - Created the .tr files for each image ```tesseract 
kor.AppleMyungjo.exp0.tif kor.AppleMyungjo.exp0 -l kor box.train ``` (both 
image got an empty .tr file)
6 - Created the unicharset file ```unicharset_extractor [box file 0] [box 
file 1]...```
7 - Created the font_properties, only has the ```AppleMyungjo 0 0 1 0 0```
8 - Cloned the tesseract repo to my mac, path ```~/projects/tesseract```
9 - cloned the langdata repo to my mac, path ```~/projects/langdata```
10 - Found the folder where the brew installed my tesseract, path 
```/usr/local/Cellar/tesseract/HEAD-f8e26ee/share/tessdata```
11 - Executed the ```~/projects/tesseract/training/tesstrain.sh``` file


```
sudo ~/projects/tesseract/training/tesstrain.sh \
  --fonts_dir /Library/Fonts  \
  --lang kor \
  --linedata_only  \
  --noextract_font_properties  \
  --exposures "0"\
  --langdata_dir ~/projects/langdata \
  --tessdata_dir /usr/local/Cellar/tesseract/HEAD-f8e26ee/share/tessdata \
  --output_dir ~/tesstutorial/kor \
  --fontlist "AppleMyungjo"
```
and got the error:

I found that the ```Fontconfig error: Cannot load default config file``` 
was being generated because of the mktemp on mac, I fixed it replacing the 
code:

training/tesstrain_utils.sh
```diff
- export FONT_CONFIG_CACHE=$(mktemp -d --tmpdir font_tmp.XX)
+ export FONT_CONFIG_CACHE=$(mktemp -d -t font_tmp.XX)
```
After executing the same code I get:
