imnoise(I,'salt & pepper',rho) but with different proportion of salt and paper

imnoise(I,'salt & pepper',rho) adds sal and paper noise to the image I so that rho percent of pixels is corrupted. However, the salt and paper is added in equal proportion. Can this be done such that we can can control also the proportion of salt to paper?

I can build this code myself. However, I was thinking maybe there is aleardy an implementation like that available online.

Hi

As of now, I can't find any direct implementation to do that. However, you can consider this file exchange submission :

I hope this will help you.
