5.3.2 Using parameterizable masks
To further improve the above implementation, it becomes necessary to free
ourselves from the hard-coding constraint. To achieve this, as was the case
with input image storing, several memory options are available, but, since the
amount of data involved in processing a mask is quite small and constant, we
considered it relevant to copy data ...
