I am, however, having trouble defining my own operations, and one of the things I do very frequently in another system, is neighborhood operations. I would like to do these things in Mathematica,and would like so help:

The built-in function ImageFilter and its documentation do not suffice?

If you want internal implementation, good luck! Take a look in the Documentation Center at tutorial/TheInternalsOfMathematicaOverview.
