[tesseract-ocr] Creating a new language pack for Javanese Script

2018-04-22 Thread Christopher Imantaka Halim 
Hi,

I want to develop an OCR for Javanese Script / Aksara.
https://en.wikipedia.org/wiki/Javanese_script

Plan on using Tesseract version 4.0
I've read the wiki but somehow got confused.

What do I need to prepare, to start the bare minimum training process? (for 
Tesseract 4.0)
In some other thread someone said that training using image files are not 
supported yet.
Also found out that box file/tiff pairs are not supported also.
(I did try making one box file, using this online 
tool: https://pp19dd.com/tesseract-ocr-chopper/)

Do we have an example of the training "inputs" somewhere on the github 
projects?

Sorry if this is a stupid question, I'm a newbie. :)

Thanks before

Re: [tesseract-ocr] Unsure why tesseract isn't returning the correct text

Yes, please use the latest code from github master branch for building.
That way you will have all the bug fixes and updates.

[tesseract-ocr] "jav" language -- is it Javanese Script or Latin-based text?

2018-04-22 Thread Christopher Imantaka Halim 
Hi everyone,

I'm new to Tesseract OCR, want to develop an OCR for Javanese Script / 
Aksara.

Noticed that Tesseract 4.0 already have a "jav" language package:

https://github.com/tesseract-ocr/tesseract/wiki/Data-Files

The question, is it for Javanese Script or for Javanese in Latin text?

https://en.wikipedia.org/wiki/Javanese_script

Thanks before
