This almost reminds of of OCR--it is just shape recognition. We use  
this for sorting and matching personalized mail pieces by machine. The  
package we use is not available to the public, but I am sure you can  
find some open source. Perhaps take a look at this project: http://code.google.com/p/pytesser/
