I was trying to implement OCR.
In that correlation is calculated b/w the input character and the images in the database (template) !!!
Why is it done so?

-------------------------------------
I'm not sure what kind of algorithms they use for OCR but I don't
think they're as simplistic as a 2D image correlation against a
template. Go here for more info:
