The MSE compares two images. You can't have an MSE with just one image - you need a reference image. Let's say the reference image is the noise free image. So the MSE of a noise-free image to a noise-free image (i.e. itself) is, of course, zero. The MSE of the noisy image to the noise-free image will be some number greater than zero.

By the way, this is done by the function immse() in the Image Processing Toolbox.
