Up: Smoothing Tasks
Smoothes an input image using the noise cheating enhancement method.
This method works only for strictly positive images. Values for adja-
cent pixels are summed until a given total is reached. Then, the total
is divided by the number of pixels added and the result is used for the
output pixel value. This smoothing is very non linear (in particular no
smoothing occur on pixels stronger than the smoothing threshold). A pa-
rameter allows to restrict the averaging to nearby pixels only: in this
case the output image is not necessarily strictly positive.
