Detailed Description

template<typename F, typename S>
struct mln::accu::count_adjacent_vertices< F, S >

Accumulator class counting the number of vertices adjacent to a set of mln::p_edges_psite (i.e., a set of edges).

The type to be count is mln::util::pix< pw::image<F, S> > where F and S are the parameters of this class.

This accumulator is used by mln::closing_area_on_vertices and mln::opening_area_on_vertices.
