Cube training tools

[Emil Julius]

Hey, I'm currently planning on writing some training tools for the Cube engine. But I would like to be sure that I'm not reinventing the wheel, as the only documentation I was able to find was: https://code.google.com/p/tesseract-ocr-extradocs/wiki/Cube

Which, I believe is written by one of the guys in this google group?

I'm currently prioritizing tools for:

* cube.size (one of the 2 bigram files)

* cube.bigrams

The tool for cube.bigrams is gonna be designed to take a plain text input file, and then calculate the bigrams and their frequency, then output in the according file format

I'm still trying to figure out a smart way to train the cube.size files, help is very welcome ;-).

Also, what's the current state of the Tesseract project in general?

"Cube is a perfect example. It doesn't do much useful, yet now everybody wants it documented, so there is no way I can commit another half-baked experiment that isn't production-ready that everybody will want documented. I have 3 new classifiers in addition to cube that haven't delivered on their early promise. It really is hard to beat the current classifier, although I am starting to understand why a little better.

The good news is that I really really want to get the Google version of the code cleaned up and synced with the outside world this quarter, as there are some improvements in there worth having.

Thank you :-)

Hi ,

  Whether there is any tool for training cube data for tesseract? since i am in need of getting trained data for Engine mode (both - TesseractAndCube) to all the languages in tessdata, If anyone already have cube data file kindly share with me, or share me the tool or procedure to get the Cube trained data for other language except English.

Thanks in Advance,

Merlin

cube training is not supported, no information is available for it. It has been deleted from the latest code.

Cube data were available only for few languages. Available data are can be found in  https://github.com/tesseract-ocr/tessdata/tree/3.04.00

along with cube data only the extraction is more accurate. Why it is been deleted?

Hi Zdenko,

     Thanks for the info, But i already took those tessdata, so only asking for the support for train the cube data for other languages which doesn't have those cube related files.

Just give us the step followed to train the language eng, hin, ita, etc., in the present tessdata repo.

Thanks and Regards,

Merlin

​As stated before, this information is not available. The training was done at Google and details were not shared since it was to be superseded by the new LSTM engine.

The answer is not going to change if you keep asking :-)​
