MATLAB: AWGN for a grayscale image

Question

Hello everyone,

I need to add AWGN to a grayscale image for the purpose of denoising. Till now I was using "imnoise" to add the gaussian noise but somewhere I doubt or I am confused whether I am adding correct noise or not.

Is this the correct method to add AWGN in an image? If not, please tell me how to add this kind of noise.

Thanking you in advance

Yes, imnoise is the right function to use.

Why are you concerned that it might not be the correct function to use?
