[tesseract-ocr] Where is /path/to/eng.user-words?

[이경준]

Hi ..


I incited this page .

I cannot find (lang).user-words .

How can I find? 


Tesseract config files consist of lines with variable-value pairs (space 
separated). The variables are documented as flags in the source code like 
the following one in tesseractclass.h:

STRING_VAR_H(tessedit_char_blacklist, "", "Blacklist of chars not to 
recognize");

These variables may enable or disable various features of the engine, and 
may cause it to load (or not load) various data. For instance, let’s 
suppose you want to OCR in English, but suppress the normal dictionary and 
load an alternative word list and an alternative list of patterns — these 
two files are the most commonly used extra data files.

If your language pack is in /path/to/eng.traineddata and the hocr config is 
in /path/to/configs/hocr then create three new files:

/path/to/eng.user-words:

the
quick
brown
fox
jumped

/path/to/eng.user-patterns:

1-\d\d\d-GOOG-411
www.\n\\\*.com

/path/to/configs/bazaar:

load_system_dawg F
load_freq_dawg   F
user_words_suffixuser-words
user_patterns_suffix user-patterns

Now, if you pass the word *bazaar* as a trailing command line parameter to 
Tesseract, Tesseract will not bother loading the system dictionary nor the 
dictionary of frequent words and will load and use the eng.user-words and 
eng.user-patterns files you provided. The former is a simple word list, one 
per line. The format of the latter is documented in dict/trie.h on 
read_pattern_list().

[tesseract-ocr] In specific Domain, What ways is suitable for training tesseract 4.00 - beta.1

[이경준]

In specific Domain, What ways is suitable for training tesseract 4.00 - 
beta.1

I can fine tunely with images or I can fine tunely with texts.

But, I want to use tesseract for business

So, I think that tesseract 's threshold > 0.95 ~ 0.975

But, My specific situation. I have torecognize All the images (I have)by 
using tesseract, And in my situation, I don't have to recoginzie all the 
images I don't have by using tesseract.

Do you know what I'm saying ?

e.g.

If ) I have 1000 images, So, I just wan to only recognize these images by 
using tesseract 4.00 - beta1.



### What about your opinion ? 

I think that tranining _ few _ layers is better than Fining tune . 

Am I right ?

[tesseract-ocr] Depending on OS, tesseract (4.0) performance is different?

[이경준]

Hi Shree, I'm using tesseract 4.0 Alpha on Ubuntu 16.04.03 LTS

But, you give me 2 scripts for tesseract 4.0 

In the scripts, They are operated by Windows . I Think.

So, I change my running enviornment of Tesseract 4.0. (Ubuntu -> Window 10)

Depending on OS, tesseract (4.0) performance is different? 

And I finally Do not solve can't encode transcription , after replacing top 
layer

I conclude that I have to change my Os.(Ubuntu -> window 10) 

Thank you

Can you check my training_text for fine tuning?

[tesseract-ocr] pango library doesn't recognize my font .

[이경준]

Hi. my name is june. Hi shree. I have a question. I'm using bash script you 
gave me.


in the script ..


# the EVAL handles the quotes in the font list
eval $tesstrain_dir/tesstrain.sh \
   --lang $Lang \
   --linedata_only\
   --noextract_font_properties \
   --exposures "0" \
   --fonts_dir $fonts_dir \
   --fontlist $fonts_for_training \
   --langdata_dir $langdata_dir \
   --training_text $langdata_dir/$Lang/$Lang.$plusTraining_text \
   --tessdata_dir $bestdata_dir \
   --output_dir $train_output_dir
 
P.S everything variables is assgined. and (e.g. fonts_for_training="Baekmuk 
Batang")


Run script(above). But I have an error . It doesn't work


So I have to delete " --fontlist $fonts_for_training " and  I make a pair 
of tesstrain1.sh & language-specific1.sh (for training_fonts) 

In this case It does work. 


I review my system (ubuntu 16.04.03 LTS) $ fc-list 

korean. 

I have lots of korean fonts 

But, it doesn't work 

Why pango library doesn't recognize the fonts I installed.

Re: [tesseract-ocr] How to replace top LSTM top layer ?

@harinath141 <https://github.com/harinath141> If you are getting a lot of 
these errors during finetune, try replace top layer training. You can use 
the box/tiff pairs generated for finetune. Commands will be similar to the 
following:

mkdir -p ~/tesstutorial/tellayer_from_tel 

combine_tessdata -e ../tessdata/tel.traineddata \
  ~/tesstutorial/tellayer_from_tel/tel.lstm
  
lstmtraining -U ~/tesstutorial/tel/tel.unicharset \
  --script_dir ../langdata  --debug_interval 0 \
  --continue_from ~/tesstutorial/tellayer_from_tel/tel.lstm \
  --append_index 5 --net_spec '[Lfx256 O1c105]' \
  --model_output ~/tesstutorial/tellayer_from_tel/tellayer \
  --train_listfile ~/tesstutorial/tel/tel.training_files.txt \
  --target_error_rate 0.01

[tesseract-ocr] How to replace top LSTM top layer ?

[이경준]

Shreeshrii  commented on 29 Jun 2017

edited 

I think this happens when the complex characters in your training text are 
not part of the original Korean Unicharset that the 4.00.00alpha 
kor.traineddata was trained with.

Do 'replace top layer' training instead of finetune. @abhishekchopde 
 has had good results with it - see #1009 


It will take longer than finetuning.



Hi shree I have a question ... you uploade this passage . But this link is 
not right . plz check again

[tesseract-ocr] I do not include 'chi_tra' in my tessdata folder . What is it ? I have seen language-specific.sh

[이경준]

Hi i'm sorry to question oftenly. and lots of questions.

But, I must use tesseract 4.0 for my business .

plz understand my situations. I have lots of family to raise.


ealier you gave me *a bash sciprt *. In there *tesstrain.sh* (course) . it 
give me an error like 


Please make sure the TESSDATA_PREFIX environment variable is set to your 
"tessdata" directory.
*Failed loading language 'chi_tra'*
Error opening data file 
/usr/share/tesseract-ocr/4.00/tessdata/chi_tra.traineddata


*Before, you gave me a conference . it froms the lang directory / 
kor.config.*





*in there #Fixes 
https://github.com/tesseract-ocr/tesseract/issues/1009preserve_interword_spaces 
1tessedit_load_sublangs chi_tra# New Segmentation search params*


So I guess "tessedit_load_sublangs chi_tra" cause to error for executing 
"tesstrain.sh"

So I conclude(for solution) *1) Delete that sentence -> Is it right ? or 
what is the side-effect*


   I want to have 1 traineddata which is fine tuned and for 2 langugages 
(korean & English)

  so is it possible to add the sentece like  *1-1)*

*"tessedit_load_sublangs eng"-> Is it right? or possible???*
*In conclusion *
*1)*


*I do not want to see like error " Please make sure the TESSDATA_PREFIX 
environment variable is set to your "tessdata" directory.Failed loading 
language 'chi_tra'Error opening data file 
/usr/share/tesseract-ocr/4.00/tessdata/chi_tra.traineddata " *

*2) If I want to use tessereract(4.0) for 2 languages(e.g. Korean, English) 
by 1(one) traineddata(which is fine tuned) *

Is it possible and How to make 1 finedtuned traineddata for 2 languages(e.g 
Korean, English) 

3) tesseract is possible to use like 

$ tesseract (picture.png) -l kor+eng

is it possible ? 

4) What is kor.vert traineddata ? (tessdata-best) 

What is different from kor.traineddata ??? 

5) Is it possible to fine tune by existing images??? How is it possible to 
use script you gave me

[tesseract-ocr] What is difference between "unicharset file" and "lstm-unicharset file"

[이경준]

Hi . Thank you for seeing my questions 

1. What is difference between 'unicharset' and 'lstm-unicharset' ?  

I know to make 'unicharset' by command line : "$ tesseract 
(lang).(filename).exp(num).tif  (lang).(filename).exp(num).box

But I don't know to make 'lstm-unicharset'  ???

cf) .tr -> .lstmf

I apply this command line = "$tesseract (lang).(filename).exp(num).tif 
(lang).(filename).exp(num) nobatch *box.train*" to tesseract 
(lang).(filename).exp(num).tif (lang).(filename).exp(num) nobatch
*lstm.train*"

2. This usage is right? 

Is it possible to apply 'unicharset' to 'lstm-unicharset'



3. In the github wiki passage

Overview of Training Process

The overall training process is similar to training 3.04 
.

Conceptually the same:

   1. Prepare training text. 
   

   2. Render text to image + box file. (Or create hand-made box files for 
   existing image data.)
   3. Make unicharset file. (Can be partially specified, ie created 
   manually).
   4. Make a starter traineddata from the unicharset and optional 
   dictionary data. 
   

   5. Run tesseract to process image + box file to make training data set.
   6. Run training on training data set.
   7. Combine data files.

The key differences are:

   - The boxes only need to be at the *textline level.* It is thus *far 
   easier* to make training data from existing image data.
   - The .tr files are replaced by .lstmf data files.
   - Fonts *can and should be mixed freely* instead of being separate.
   - The clustering steps (mftraining, cntraining, shapeclustering) are 
   replaced with a single slow lstmtraining step.


I think that In The key differecen section "unicharset" are replace by 
"lstm-unicharset"  - sentence is added 

Am I false 



I wait everybody's answers

Thank U. Have a nice day!

Oh. I know ㅜㅜㅜ Thank u  I was really impressd by U 

OK. Thank you very much 

Last question ... I can not understand .. trainned  data type

Your saying means that in the tesseract 4.0 / tessdata_best is better than 
tessdata  // ㅜㅜㅜ 

what is the tessdata_fast  ㅜㅜ  Fast integer versions of trained 
models

ㅜㅜ Sorry ㅜㅜㅜ ㅜplz help me ...

Re: [tesseract-ocr] Re: I'm reading Using tesstrain (tesseract 4.0) wiki passage _ I have a question

[이경준]

No. I'm really Sorry about complaining about tesseract(4.0) 

I mean that tesseract is great , but is not perfect(100%) 

I think that Tesseract is fairy good.

But, I have a clue about customizing and using Tesseract(4.0) rightfully

Thank U.

At first I know the trainneddata is 3 types

tessdata / tessdata_fast/ tessdata_best /

so, I used tessdata - kor.trainneddata to check tesseract(4.0) test ..

and you give me a right answer about using tesseract .(another questions I 
wrote to you)

<https://lh3.googleusercontent.com/-LJk-KTYwO8M/Wpf00BT2O5I/Mw0/3VfqA5FPzd8Ued9xBWcF1VrvNKm9NKz5wCLcBGAs/s1600/0301_2.png>


But, you suggest use tessdata_fast ? I have no idea .. ㅜㅜㅜ

And. once upon a time I used tessdata_best / tessdata_fast /tessdata 3 type 
use respectively,

But correctness is the best data is tessdata .. 


<https://lh3.googleusercontent.com/-_PSt4nXFW2U/Wpf1mHFHAiI/MxA/zPfyMZG-j14kqwb85eOR0ALF3TwfvSm2gCLcBGAs/s1600/0301_1.png>


In the github page descption says that tessdata_best is best accuracy in 3 
types tessdata...

But in actual is not right .ㅜㅜ Correct rate is fairy different tessdata 
from tessdata_best

So I use the tessdata . What makes me give me a that result

So. your last (recently) answer & sugestion  = in this passage 

you give me a suggestion  that in the command line to type " 
combine_tessdata -u kor.traineddata 

What is that meaning ? Could you explain for me ? 

(in short) 

1. I want to tesseract 4.0 using rightly in my business

so i have a plan using trainneddata.

 case  #1
if  already made and uploaded github page - 3 type trainned data( tessdata 
/ tessdata_best / tessdata_fast) is  not good enough to use Korean in my 
business

 I would to make a  customized and trainned "New trainneddata"

But how can i make a decsion about that / I can make a treshold to help a 
descision  


Plz help me  ㅜㅜ

[tesseract-ocr] I have a question about making a traineddata (tesseract 4.0 LSTM)

[이경준]

Hi 

I have a question about making a traineedata (tesseract 4.0 LSTM)

Tutorial Guide to lstmtraining 
Creating
 
Starter Traineddata

NOTE: This is a new step!

Instead of a unicharset and script_dir, lstmtraining now takes a traineddata 
file 
on its command-line, to obtain all the information it needs on the language 
to be learned. The traineddata *must* contain at least an lstm-unicharset
 and lstm-recoder component, and may also contain the three dawg files: 
lstm-punc-dawg 
lstm-word-dawg lstm-number-dawg A config file is also optional. The other 
components, if present, will be ignored and unused.

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.




above the passage  I could not find to make a 'lstm-unicharset' ... So 
I have no idea 


and. I have a 
question https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00 


NOTE Tesseract 4.00 will now run happily with a traineddata file that 
contains *just* lang.lstm, lang.lstm-unicharset and lang.lstm-recoder. The 
lstm-*-dawgs are optional, and *none of the other components are required 
or used with OEM_LSTM_ONLY as the OCR engine mode.* No bigrams, unichar 
ambigs or any of the other components are needed or even have any effect if 
present. The only other component that does anything is the lang.config, 
which can affect layout analysis, and sub-languages.

If added to an existing Tesseract traineddata file, the lstm-unicharset doesn't 
have to match the Tesseract unicharset, but the same unicharset must be 
used to train the LSTM and build the lstm-*-dawgs files.




at the end of this wiki passage, trainned data is composed by 'lang.lstm, 
lang.lstm-unicharset, lang.lstm-recoder'(mandatory) /



but firstl `Creating Starter Traineddtat' passage says that trainned data 
is composed by 'lstm-recoder, lstm-unicharset(mandatory) /



Which is sentence is right? 


plz help me.

Thank U reply my question.

But my system is operated by Ubuntu 16.04. 03 LTS 

I think that that path is not working  ? Am I false?

[이경준]

Sorry . But I have issue about korea 

you mentioned answer is applyed to english . But , it doesn't work korea

In the logs . Font error . But I refer to the /training/language-specific.sh

vi language-specific.sh 

Font list - kor _NeoLatin

so I install korean fonts in there .

and reboot 

but same result .. Is it possible to solve korean font issue?

[tesseract-ocr] I'm reading Using tesstrain (tesseract 4.0) wiki passage _ I have a question

[이경준]

Hi I'm studying this passage. But I cannot understand  what is that meaning 
flag "--noextract_font_properties" ? . so I saw the file 
/tesseract/training/tesstrain.sh  

But I cannot Find "--noextract_font_properites"

Here usage : 

# USAGE:
#
# tesstrain.sh
#--fontlist FONTS   # A list of fontnames to train on.
#--fonts_dir FONTS_PATH # Path to font files.
#--lang LANG_CODE   # ISO 639 code.
#--langdata_dir DATADIR # Path to tesseract/training/langdata 
directory.
#--output_dir OUTPUTDIR # Location of output traineddata file.
#--overwrite# Safe to overwrite files in output_dir.
#--linedata_only# Only generate training data for 
lstmtraining.
#--run_shape_clustering # Run shape clustering (use for Indic 
langs).
#--exposures EXPOSURES  # A list of exposure levels to use (e.g. 
"-1 0 1").
#
# OPTIONAL flags for input data. If unspecified we will look for them in
# the langdata_dir directory.
#--training_text TEXTFILE   # Text to render and use for training.
#--wordlist WORDFILE# Word list for the language ordered by

#
# OPTIONAL flag to specify location of existing traineddata files, required
# during feature extraction. If unspecified will use TESSDATA_PREFIX 
defined in
# the current environment.
#--tessdata_dir TESSDATADIR # Path to tesseract/tessdata directory.
#
# NOTE:
# The font names specified in --fontlist need to be recognizable by Pango 
using
# fontconfig. An easy way to list the canonical names of all fonts 
available on
# your system is to run text2image with --list_available_fonts and the

Using tesstrain

The setup for running tesstrain.sh 

 is 
the same as for base Tesseract. Use --linedata_onlyoption for LSTM 
training. Note that it is beneficial to have more training text and make 
more pages though, as neural nets don't generalize as well and need to 
train on something similar to what they will be running on. If the target 
domain is severely limited, then all the dire warnings about needing a lot 
of training data may not apply, but the network specification may need to 
be changed.

Training data is created using tesstrain.sh 
 
as 
follows: Note that your fonts location may vary.

training/tesstrain.sh --fonts_dir /usr/share/fonts --lang eng --linedata_only \
  --noextract_font_properties --langdata_dir ../langdata \
  --tessdata_dir ./tessdata --output_dir ~/tesstutorial/engtrain



Thank U Very much . I want to reply Everybody

[tesseract-ocr] I have a Question about Creating Traing Data

[이경준]

Hi 
I'm KOREAN
I'm studying Tesseract 4.0 
https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00
This page is very useful to study tesseract 4.0

But, I'm poor at Reading English & Understanding Tesseract training 4.0 
In short, the next senentes cannot be understood by me.

*Creating Training Data*

As with base Tesseract, there is a choice between rendering synthetic 
training data from fonts, or labelling some pre-existing images (like 
ancient manuscripts for example). In either case, the required format is 
still the tiff/box file pair, except that the boxes only need to cover a 
textline instead of individual characters. 'Newline' boxes with tab as the 
character must be inserted between textlines to indicate the end-of-line. 
Multi-word boxes require a different box format, as the space would confuse 
the parser

I have no idea  Could you explain this sentence to me & I want to see 
the example of the box file /tiff (by tesseract 4.0) 

Thank you .
