While you can't compress the random noise itself, it's often easy to still get decent compression of the whole image, depending on how serious the noise is. Imagine an image with large blocks of constant colour in 8-bit colour depth has 2 bits of random noise on every pixel. We indeed can't ever compress to less than 2 bits per pixel, but we can still get down to that. |
