This is my target image: 
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? -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
