16.4 Cumulative Function
called cumulative function calculates the
mean values over a pixel and a specified buffer areas around it. The dimension
defines the number of pixels in each direction over which the mean values are

for one pixel|
Multiple application of the cumulative function leads to a relative weighting of the
sourounding pixels according to their proximity.
