Use this formula:confidence = min(100, max(0, 100 + 5*certainty))
where "confidence" is the value you need, "certainty" - the value

Hi Dmitri

Does your formula only for negative confidence score or for all?

Because i am getting confidence score for "Name" - 215(positive value) Is it correct or not? or Does i do any calculation for that?

Looking forward your reply.

Guna

It seems you're confusing "certainty" and "confidence" here. Please pay close attention to what you're writing or rephrase your question. The formula itself allows no values out of the [0, 100] range.

Really sorry for the mistake.

I am getting certainty value from tesseract for Text "Name" 215(Positive value). 

Does your formula applicable for this certainty value?

Kindly do the needful.
