Detailed Description

median filter with circular element

This image processing class is implemented using the vipl filters, which means that it can be used with any image class (IUE or not, TargetJr or not, vil or vil1 or not) of any pixel data type.

vipl_median filtering is an operation that replaces a pixel with the median 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 operator>(DataIn,DataIn) is being used; for non-scalar data types (like colour pixels) an appropriate ">" 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!
