Type alias for a neighborhood defined on the 2D square grid with integer coordinates.
A neigh2d can be constructed from a window2d. Compared to a window, a neighborhood does not include the central point.
window2d neighb2d - o - - o - o o o --> o x o - o - - o -
Common 2D neighborhoods are predefined and can be used directly: mln::c2_row(), mln::c2_col(), mln::c4(), mln::c6_2d(), mln::c8(). An exhaustive list can be found in section 2D neighborhoods.
The list of dpoint2d included in a neighb2d is accessible from window2d::std_vector() method or simply by iterating over this list:
Iterating over the neighbors of a specific point is performed thanks to n-iterators, as follows:
It also works while iterating the sites of an image domain:
