You can do this with the use of artificial neural network (for character recognition). There are externals for Pd : http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/externals/ann/
Is it just me, or it sounds like it's going to take a lot of preprocessing before you can even think of feeding it to a neural network ?
Human vision is made of a lot more layers of neurons than we can hope to deal with in artificial networks.
At what angles should characters be recognised ?
Which colour on which colour ?
You better settle those things first, so that you can figure out how you can reduce your data beforehand.
But making an OCR using ANN is a lot lot more work than using an OCR library. Making a Pd-to-OCR-library interface is less work than making an OCR abstraction library... and it isn't necessarily because Pd would be bad at it (I don't know about that). It's more because it takes a lot of knowledge to make an OCR library from nearly scratch.
