Training Tesseract Arabic/Hindi Digits using JTessBoxEditor in window 10

[Marwa M. Khan]

Hello, 

   I am trying to train the Tesseract 4.0 with LTSM on  Arabic/Hindi Digits in windows OS. I found that I need to create box file. Thus, I'm using JTessBoxEditor 2.0 for creating tiff and box files. However, it fails when I used JTessBoxEditor 2.0  to generate the .traindata file. Note that I choose combine_tessdata.exe as tesseract executable, ara.arial.exp0.box as training data, and training with existing box as a training mode. 

The output is the followings:

esseract Open Source OCR Engine v4.0.0-beta.1-108-gf291 with Leptonica

Could you please tell me where I did wrong or how to fix this error?

Bad box error might be due to the images that you are using to train in jtess box editor .

Check the resolution of the images.
