What do you mean with blur? Are you refering to Texture Filtering? Because Blur is something different in Graphics Programming.. So to prevent unwanted answers..

You would render the scene to a texture, then render a quad with that texture applied on it. For each pixelfragment (pixel shader) you'd take the surrounding pixels and use your formula to calculate the final outputpixel.

For DOF, you'd most probably use the Z in the formula..
To be honest, don't know the exact implementation.. So I can't help you. But do look at nvidia's developers website. You can find a lot of (FX) shaders there.
