Smoothing noise effect

Smoothing noise effect is mostly used to smooth images with limited color range, e.g. GIF files or 1 bit images. Still, this effect can also be applied to full color images. This filter adds noise to contrast edges of the image; the contrast of added pixels is similar to that of the original.
