Hi guys,
I want to recognize handwriting shape and figure out which shape it probably is in the set. Simply saying, if I draw a triangle, the application should recognize it as an triangle.
How can I do this using C# or java, any help is appreciated.

Thanks in advance.

This is Simple. First u need to train ur code for different input shapes. This can be done by Dividing ur draw area into Grid. Now the square which is covered by Black (Written part) is taken as binary 1 and the area which is not covered with binary 0. Suppose say user has written A then divide A area into grid (Grid Should be fixed always). then see which square has been touched by it and which n all are not. Touched ones u can assign as 1 and other 0. Like wise u hav to train for all ur Sets and pre store it. Whenever something is entered compare with ur sets.This is Simple way of dealing with Alphabets.

I m new to this kind of thing, so forgive me if this is a stupid question.

From what I understood, this has done to identify handwriting rite, so you are saying I can use the same thing to identify shapes!!!
