My PHYS341 students were interested to see how the OCR routine processed their attendance sheet, so I applied it, as shown below.
The left panel shows the original, the right the transformed version. The routine did a reasonable job of un-distorting the page (although it wasn’t too bad to begin with).
And here’s what the routine returns as text:

…not great.
I’m not totally sure what went wrong. Maybe I should have them write their student numbers instead.
UPDATE: 2016 Feb 5
Here’s another go with a different attendance sheet. Not much better.
