You can use imnoise().
But I hope you realize that it's kind of artificial (what that function does) and you'll never see Poisson noise in any real world situation unless you're dealing with extremely low light levels - basically photon noise limited imaging like you'd get in astronomy, nuclear medicine, or fluorescence microscopy. I'm talking about like 20 or so photons per pixel. You'll never get it from your basic snapshot or video with a normal digital color camera taking images of your office or lab. What are your images from? There are other kinds of noise that might be more applicable. See
