Maybe look at the API [1]. The output of the attached program shows there’s a
lot of detail that can be gleaned at this level, including the confidence of
the selected character and that of the other candidates. Compiling against
tesseract on Ubuntu, at least, is fairly straightforward. I don’t know about
windows or os/x.

Subject: Re: [tesseract-ocr] How to get digital and the confidence?
I think that is another question. I want to filter recognized characters by
confidence in this question but don't know how to get the confidence with
Tesseract.

Your image is 96 dpi. Increase the dpi to 300 and try.
Preprocess the image to remove the boxes around letters, if possible.

Actually my question is similar to [this
post](https://stackoverflow.com/questions/4944830/how-to-make-tesseract-to-recognize-only-numbers-when-they-are-mixed-with-letter).
But I don't know why the following answer will lead to another direction. I
mean, I just hope to get those digits with high degree of confidence. Such as I
can do this with another language
Then I can just keep those degree of confidence with a threshold `0.9`. But now
I hope to use *Tesseract* to do this.
First, I train a *number.traineddata* just for recognizing number. You can get
it [here](https://1drv.ms/u/s!Aumb0ijJibxOi1KVXFjwDzOVRQrm).
tesseract.exe target.jpg stdout -l number --oem 0 -psm 6
Note I will get all digits which include high confidence and low confidence.
Can we recognize the number and get the degree of its confidence? I cannot find
any information to implement it. If *Tesseract* cannot do it. Any other method
based on **C++** can implement my target? Could anyone can give me some
information for it?
