different outputs from same image while using Tesseract 3.0.5

[Canberk Ozdemir]

Hello all,

I couldn't find any post related to the subject. Is it possible that Tesseract can -slightly- give different outputs running on the same image in different runs (with same configurations.)

In some scanned documents having some noises, I get some different characters in outputs. I can say %95 of characters are the same.

Regards,

I had the same problem, getting different outputs between 3.04 and 3.05, the only solution i've found was to upgrade to tesseract 4.0

Hello David,

Yesterday, a colleague of mine figured out that when a Tesseract variable called classify_enable_learning is disabled, it no longer gives different results. 

I think these variables are stated here with their descriptions --> http://www.sk-spell.sk.cx/tesseract-ocr-parameters-in-302-version

Hi Canberk,

Thanks for your answer, i didn't know about that variable.
