OCR OC-gain

Posted by admin on January 20, 2016
Posted in: Data Science. Tagged: data science, OCR.

My PHYS341 students were interested to see how the OCR routine processed their attendance sheet, so I applied it, as shown below.

IMG_3707_orig-scannedThe 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:

zolto J:)o<-&\

$030-4 “10u\J ‘

…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.
