[Olena] #161: Implement more complex psite iterators

by Olena

#161: Implement more complex psite iterators ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: task | Status: new Priority: major | Milestone: Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- As of r2148, we only have a single piter couple on complex : `mln::p_complex_fwd_piter_` and `mln::p_complex_bkd_piter_` (source:trunk/milena/mln/core/p_complex_piter.hh:2148). Comments (FIXMEs) at the end of source:trunk/milena/tests/core/complex_image.cc:2148 suggest to add these additional iterators: * iterators on ''n''-faces with ''n'' fixed in [0, ''d''] (using `mln::p_faces` and `mln::faces_psite`?) * iterators on ''n''-faces with ''n'' in a subset of [0, ''d'']; * etc. -- Ticket URL: <https://trac.lrde.org/olena/ticket/161> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #162: Implement windows, neighborhoods, and corresponding iterators for complex-based images

by Olena

#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.

[Olena] #159: Distribute SWIG wrappers

by Olena

#159: Distribute SWIG wrappers -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: minor | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- According to Alexandre Hamez, files generated by `swig` (e.g., `*.py` and `*-wrap.cc`) are portable. We should distribute them, as * it would save users wanting to use Swilena some time; * it would free them to have SWIG to compile Swilena. To do: * distribute these files (remove `nodist_` prefixes); * ensure they're available at distribution time (use `dist-hook` in `Makefile.am`); * add generated files to `MAINTAINERCLEANFILES`; * adjust `configure.ac`?
