#162: Implement windows, neighborhoods, and corresponding iterators for complex- based images ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: task | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- For a given (fixed) dimension ''n'' and a psite ''p'' on a ''n''-face, implement windows/neighborhoods (and corresponding iterators) returning * the set of (''n''-1)-faces adjacent to ''p'' (using ``mln::p_faces`` and ``mln::faces_psite``?); * the set of (''n''+1)-faces adjacent to ''p'' (using ``mln::p_faces`` and ``mln::faces_psite``?); * the set of ''n''-faces sharing a (''n''-1)-face with ''p''; * the set of ''n''-faces sharing a (''n''-1)-face or (''n''-2)-face (by transitivity) with ''p'' (is it useful?); * the set of the faces in the ``cell'' including ''p'' (named ``''p''-hat'' in couprie.08.pami), i.e., the set of all ''m''-faces adjacent to ''p'', where ''m'' is in [0, ''n''-1].[[BR]] In that definition, ''p'' is said adjacent to an ''m''-face ''q'' if there is a sequence (''m,,1,,'', ''m,,2,,'', ..., ''m,,k,,'') of faces so that * ''m,,1,,'' is an (''n''-1)-face adjacent to ''p'' ; * ''m,,2,,'' is an (''n''-2)-face adjacent to ''m,,1,,'' ; * ... (and so on) * ''m,,k,,'' is an (''m''+1)-face adjacent to ''q''. * what else? As in #139, we might want to factor things using implementation classes: * ``mln::internal::complex_vicinity`` * ``mln::internal::complex_vicinity_piter`` We might even be able to factor them with graph-based ones. -- Ticket URL: <https://trac.lrde.org/olena/ticket/162> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.
