Adding Noise to RGB Image

I am trying to add salt and pepper noise to an RGB Image WHERE the noise density of pepper is 0.1 and the noise density of salt is 0.2. How can I do it?

Refer the following File Exchange link, to add Salt or Pepper noise with certain densities.

Fore the color image, might be apply to all individual image planes, later do the concatenation

niseyIm=cat(3,NoisyR,NoisyG,NoisyB)

Disclosure: I have not tested the above suggestion.

See attached demos where I add salt and pepper noise, then remove them with a modified median filter.
