Unable to identify Zero - From dot matrix image

[hari kumar]

Basically, I'm are trying to extract the text from an image (after processing the original dot matrix image using Java & Open CV).

We have a little hard time with identifying the number Zero, apart from that we are able to identify all other numbers from the image.

 

The zero is being detected as 3,6 or 8 and we could see there is a stripe in the middle of the zero, So just thought of taking your help out here to resolve this issue.

 

Currently, we are using OCR-Tesseract to extract the text in the image and zero is not been identified.
