Simple pattern recognition from paper: knowledge test

Question

I want to make an app for test validation (on paper) with the camera (ex. android). Accordingly, I need to recognize filled response options on a paper, which I will do in advance.

Prompt, where to start? Where to dig? I know of the existence of the library OpenCV - it will help me?

Thank you.

For me the best you can do is start playing with some QRCode lib to understand how the pattern recognize works for pictures... — GhostDerfel, Feb 10 '14 at 20:08
So it's some kind of multiple choice, no need to recognize handwritten words, right? — FD_, Feb 10 '14 at 20:09
