Noise Filter            Description                                Output
                  CIE lch Noise filter According  to  CIE  standards,  the  CIE
                                  lch Noise filter generates noise in the
                                  active layer or selection by using the
                                  Lightness, Chroma, Hue colour model.










                  RGB Noise Filter  The RGB Noise filter adds a normally
                                  distributed  noise  to  a  layer  or  a
                                  selection.  It  uses  the  RGB  colour
                                  model to produce the noise (noise is
                                  added to red, green and blue values
                                  of each pixel). A normal distribution
                                  means  that  only  minor  noise  is
                                  added to the majority of pixels in the
                                  affected  area,  while  more  extreme
                                  values affect fewer pixels.

              Edge Detection Filters

              Edge detect filters look for lines separating various colours so they can identify an object’s features. They are employed
              in many creative activities. Before applying edge filters, some blurring is frequently required because it flattens tiny
              signal ripples and prevents false edges.

                                      in  artificial  vision,  and  it  runs  fairly
                                      quickly because there are effective ways
                                      to create Gaussian blurs.
