Lack of accuracy on reading numbers

[Ajay Pandya]

Hello Everyone,

I am using tesseract 5.2 with C#. Having problem in reading this number.

PSM : 8

OEM : 3

Train file : eng (Best)

Data : 31111, Reading 3111.

We have many same images with different numbers. Sometimes it adds extra number and some times it removes. 

Kindly help with this problem.

Thanks.

Always test the command line if there is an issue with the wrapper.

C 3111

seem like psm 8 is not suitable in this case.
