Look into this field to find why the data doesn't get detected correctly.

The field has '1 ch' -- the 1 doesn't get detected because it occupied an area of 48 pixels, therefore it doesn't pass the valid_area() check.

I am wondering if we can change the valid_area check to be based on the total area of the image. Some fields are bigger than others so, for a small field with a 1 that occupied 48 pixels maybe that's a big enough area to pass it as valid.

UPDATES on the last comment: I tried to change the code so that the area would be based on the total area of the field but this leads to other strokes, that we don't want, also being detected -- overall, I don't think the gain of 1's and i's we would get from this change would be worth corrupting multiple of the other fields.

The next issue with this field is that 'ch' are connected by the same hand stroke. Word_segmentation algorithm is not finding a segmenting line between the two characters. This depends on the amount of pixels on the vertical line that separates the two letters.

HELP NEEDED: Check with Dr. Olschanowsky how to proceed - changing the vertical histogram code is not advised. Maybe we just can't fix this instance
