Having issue with Italic characters

[Muhammad Shamim]

Hi,

I am using  tesseract-ocr-setup-3.05.00dev.exe to do OCR and its working fine for me with default training data files .
Only facing issue with Italic character .
e.g
     Italic "l"   => "/"
     Italic "i"   => "/"
Anybody has idea to deal with this issue ?
Any extra step need to do ?

Thankyou

Use Tesseract 4.0.0alpha and --oem 1 for LSTM. It works ok with that. 

--oem 0 with legacy engine gives / instead of i.

you could test to see if a  better dpi image(300 dpi)  works with the legacy engine.

Thanks Shree,

That's a nice suggestion to get it, sure I will try it and let you know .
One more thing do you have any idea about the JAVA wrapper library on top of Tesseract 4.0.0 ?

thanks again
