Apply a non defined noise to an image

Hello!
I have a user defined function that lets us set some kinds of noise and I want to apply that noise to an image. How can I do this since the imfilter function only allows us to apply pre defined noises?
Thank you in advance

imfilter() does not apply noise. Maybe you got it confused with imnoise().
You're going to have to be more specific than that. For example is the noise independent of the signal and adds onto it? Or does the noise depend on the value of the signal? Give an example of some noise function that you might want to apply.

yes,sir,may be define the noise matrix and add to image ,such as
x = imread('carmeraman.tif');
nx = double(x) + 18*randn(size(x));
