Noise Filter            Description                                Output
                    HSV Noise Filter  Causes  variations  in  the  hue,
                                     saturation, or luminosity value of an
                                     image.











                    Hurl             This  noise  filter  adds  random  pixels
                                     to  the  image,  giving  it  a  distorted
                                     appearance.











                    Slur             By sliding the pixels downwards, Slur
                                     creates  a  ragged  edge  on  all  of  the
                                     components in an image.











                    Pick             Changes  out  a  few  pixels  with
                                     neighbouring ones.













                    Spread           This filter works by swapping a pixel
                                     in  one  location  with  a  randomly
                                     selected  pixel  from  another  source
                                     while  taking  colour  transitions  into
                                     account.
