[tesseract-ocr] Re: tess-two with tessdata_fast crashes

2019-12-08 Thread NY C 
I know there are new OcrEngineMode value in Tesseract.
But not in tess-two.

In tesseract 4.x, ocrEngineMode is :

enum OcrEngineMode {
  OEM_TESSERACT_ONLY,   // Run Tesseract only - fastest; deprecated
  OEM_LSTM_ONLY,// Run just the LSTM line recognizer.
  OEM_TESSERACT_LSTM_COMBINED,  // Run the LSTM recognizer, but allow 
fallback
// to Tesseract when things get difficult.
// deprecated
  OEM_DEFAULT,  // Specify this mode when calling init_*(),
// to indicate that any of the above modes
// should be automatically inferred from the
// variables in the language-specific 
config,
// command-line configs, or if not specified
// in any of the above should be set to the
// default OEM_TESSERACT_ONLY.
  OEM_COUNT // Number of OEMs
};

However, in the newest release of tess-two, the ocrEngineMode is :

@IntDef({OEM_TESSERACT_ONLY, OEM_CUBE_ONLY, 
OEM_TESSERACT_CUBE_COMBINED, OEM_DEFAULT})
public @interface OcrEngineMode {}
public static final int OEM_TESSERACT_ONLY = 0;
@Deprecated
public static final int OEM_CUBE_ONLY = 1;
@Deprecated
public static final int OEM_TESSERACT_CUBE_COMBINED = 2;
public static final int OEM_DEFAULT = 3;

If there is no way to set OEM_LSTM_ONLY in tess-two,
I can only assume this is a bug in tess-two.

 Hi,
 I want to use tesseract for Chinese words. So, first I tried to execute 
 the command 
 sudo apt install tesseract-ocr-chi-sim 
 And, I can find chi_sim.traineddata in 
 /usr/share/tesseract-ocr/4.00/tessdata and can check like this (I also 
 downloaded chi_tra and jpn.)

 $ tesseract --list-langs

 List of available languages (5):

 chi_sim

 chi_tra

 eng

 jpn

 osd


 Actually, I can use tesseract, but I want to do ocr more accurately, so 
 I want to use chi_sim.traineddata downloaded from here.

 https://github.com/tesseract-ocr/tessdata/blob/master/chi_sim.traineddata
 After I executed the command
 sudo apt remove tesseract-ocr-chi-sim
 I put the new chi_sim.traineddata in 
 /usr/share/tesseract-ocr/4.00/tessdata, and I tried to use tesseract. 
 However I cannot like this.

 $ tesseract 0.jpeg output -l chi_sim

 Please make sure the TESSDATA_PREFIX environment variable is set to

 Please tell me why I cannot use the traineddata downloaded from

Re: [tesseract-ocr] tess-two with tessdata_fast crashes

2019-12-08 Thread NY C 
I see.

However there are only 4 OEM parameters I can find in tess-two sorce code :

@IntDef({OEM_TESSERACT_ONLY, OEM_CUBE_ONLY, 
OEM_TESSERACT_CUBE_COMBINED, OEM_DEFAULT})
public @interface OcrEngineMode {}

/** Run Tesseract only - fastest */
public static final int OEM_TESSERACT_ONLY = 0;

/** Run Cube only - better accuracy, but slower */
@Deprecated
public static final int OEM_CUBE_ONLY = 1;

/** Run both and combine results - best accuracy */
@Deprecated
public static final int OEM_TESSERACT_CUBE_COMBINED = 2;

/** Default OCR engine mode. */
public static final int OEM_DEFAULT = 3;

I sincerely can not find a suitable OEM parameter. I don't think there is 
any other OEM parameter in tess-two.
(Again, the version I use is https://github.com/alexcohn/tess-two 

,  9.0.0)

Could you please give me some more tips.

Re: [tesseract-ocr] I cannot use traineddata downloaded from Data Files

2019-12-08 Thread 坂本聖 
Thanks for your advice.
I downdloaded files by clicking the "download" button in 
https://github.com/tesseract-ocr/tessdata/blob/master/chi_sim.traineddata.
And I moved the chi_sim.traineddata file 
to  /usr/share/tesseract-ocr/4.00/tessdata/ , and checked the file (which 
size is 42.3MB)  exactly there.
But, I cannot use tesseract.
As I said, I can use tesseract with the file downloaded by executing sudo 
apt install tesseract-ocr-chi-sim, but the data downloaded from Data files 
did not work.
I cannot understand why it did not work.

[tesseract-ocr] Re: I cannot use traineddata downloaded from Data Files

2019-12-08 Thread 坂本聖 
Thanks for your advice, however I am using ubuntu on wsl (windows subsystem 
for linux), and I have already tried to set TESSDATA_PEREFIX by executing $ 
export TESSDATA_PREFIX=/usr/share/tesseract-ocr/4.00/tessdata/  .
But, I cannot use tesseract.
If I use the traineddata downloaded from sudo apt install 
tesseract-ocr-chi-sim, I can use tesseract with the data downloaded from 
data Data files.
Cannot I use tesseract on wsl (Ubuntu)?

Re: [tesseract-ocr] tess-two with tessdata_fast crashes

2019-12-08 Thread Zdenko Podobny 
If you want to use API you need to spend some time with docs and source
code.
You could fine out quite quickly that  CUBE  was removed from tesseract and
is not available in version 4.
