Detailed Description

morphological erosion with circular element

Erosion is a morphological operation that replaces a pixel with the minimum 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 min(DataIn,DataIn) is being used; for non-scalar data types (like colour pixels) an appropriate min() 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!
