Determining noise in a color image
I want to estimate noise in a color image. I need to determine if the image is too noisy. Could someone please guide me on how to proceed about this?

I think that the simplest way to calculate the noise in an image would be to compute the standard deviation between the original image and its smoothed copy.
However that might not work for any case, therefore in such a case it would be better to calculate the FFT of the image and use a high frequency components for noise estimation. Have a look in this answer from SO.
