Hi Abhishek,
hope you are doing well.
What you need to do is to pre-process the image. Conver it to binary file or invert the colors to black and white. then what you can do is use opencv to draw a contour on the number. then that contour can be cut out and sent to tesseract.
I can provide you the contour detection coe if you want. Revert back for any query.
Keep up the good work.
