  Hi!

I am doing a nice little OCR for some numbers. See the attached image. I 
can identify each number as an object. When I look at each object's 
attributes, I see a fatal similarity between the number '6' and '9':

0: Size: 18 - Elongation: 1.44449 - Flatness: 1.44449 - CentroidY: 6
1: Size: 10 - Elongation: 3.65503 - Flatness: 3.65503 - CentroidY: 6
2: Size: 15 - Elongation: 2.06489 - Flatness: 2.06489 - CentroidY: 6
3: Size: 15 - Elongation: 1.86812 - Flatness: 1.86812 - CentroidY: 6
4: Size: 16 - Elongation: 1.63288 - Flatness: 1.63288 - CentroidY: 6
5: Size: 17 - Elongation: 1.7793 - Flatness: 1.7793 - CentroidY: 6
6: Size: 19 - Elongation: 1.54404 - Flatness: 1.54404 - CentroidY: 6
7: Size: 12 - Elongation: 2.50164 - Flatness: 2.50164 - CentroidY: 7
8: Size: 19 - Elongation: 1.53748 - Flatness: 1.53748 - CentroidY: 6
9: Size: 19 - Elongation: 1.54404 - Flatness: 1.54404 - CentroidY: 6

Which means, that I can't distinguish '6' from a '9'. Does anybody have 
any idea how I could do that?

Best regards,
Christian
