You now need a recogniser. You could use a neural network library or
an adaptive classifier. Tesseract-OCR, the one I am trying to adapt,
used a neural net named aspirine/migraine previously and then switched
to a nearest-neighbour based adaptive classifier engine. This switch
was made due to licensing issues with aspirine i believe.
The challenge ofcourse is not to build a recogniser, since you can use
one of the available ones. The challenge is to gather sufficient
training data, or better yet, create a tool that automatically
generates training data  (given a font name and size) for this OCR
system using image rendering in a matter of seconds.
I have been  trying to do it but my initial approach was wrong.
However I believe I now know the correct approach.
