I've to write a program which is able to recognize patterns, specially characters. I've implemented back-propagation in c# and now I want to use it for the pattern recognition. I've also created a form application and used brush/graphics so that user can write something with the help of mouse (just like 'pencil tool' in MS Paint). So I need some helping material about "How to implement character recognition method in my application?".
Helping stuff over the internet mostly related to back-propagation and software demos.
