Detailed Description

morphological dilation with circular element

Dilation is a morphological operation that replaces a pixel with the maximum value of its surrounding pixels, in a certain neighbourhood. Here, the neighbourhood is circular, with an arbitrary (float) radius, which is to be passed to the constructor.

Note that the function max(DataIn,DataIn) is being used; for non-scalar data types (like colour pixels) an appropriate max() function must thus be supplied.

Note also the implicit use of DataOut::DataOut(DataIn), which you probably will have to provide when DataIn and DataOut are not the same type. It could even be argued that these types should always be the same!

            agreed) ctor and to use preop and postop to define/destroy the mask.
