JQUERY/JS: Simple OCR for a simple math operations

Question

Hi to all Dear Coders,

i have opened this new question because i would like to make a simple script in Jquery or Javascript that read from very simple images the figures. This is an example of image:

And this is an easy tutorial how to make: TUT Math Image

And then i have see this script that read all phrases: Megaupload auto-fill captcha

My idea is that recognizes single figures and then save this in a variable.

Excuse for my disturb.

Thanks in advance for all.

Kind Regards.
