#149: Revamp util::graph -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- * Get rid of superfluous dynamic allocations (w.r.t. vertices & edges handling). * Move properties attached to vertices and edges out of the graph (this should allow the merging of `util::graph` and `util::internal::graph_base`. * Allow the removal of vertices and edges. Don't forget to warn users about the invalidation of vertex and edge ids (handlers). * Stop using the term « id » (« identifier ») for vertices and edges, and prefer the term « handler » ? (The BGL call them « descriptors ».) All these changes might bring us closer to the BGL' `adjacency_list`. See how we could factor things, while not requiring a dependency on the BGL. -- Ticket URL: <https://trac.lrde.org/olena/ticket/149> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #171: Complete and factor the classic/regular point types

#171: Complete and factor the classic/regular point types ------------------------------+--------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: task | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: code duplication | ------------------------------+--------------------------------------------- Several tasks, that may be performed independently: * Add `mln::point1df` and `mln::point2df`.[[BR]] (Class `mln::point3df` is already implemented, see source:branches/cleanup-2008/milena/mln/core/alias/point3df.hh.) * For ''N'' in {1, 2, 3}, factor the implementation of `mln::point`''N''`d` and `mln::point`''N''`df`.[[BR]] (See * source:branches/cleanup-2008/milena/mln/core/alias/point3d.hh, and * source:branches/cleanup-2008/milena/mln/core/alias/point3df.hh, which share most of their code!) Remark: all these types are located in `mln/core/alias/`, but they are more than mere aliases; move them elsewhere? -- Ticket URL: <https://trac.lrde.org/olena/ticket/171> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

#153: Write a test using Ubigraph -----------------------------------+---------------------------------------- Reporter: levill_r | Owner: Olena Team Type: task | Status: new Priority: trivial | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: rendering third-party | -----------------------------------+---------------------------------------- Ubigraph is a promising graph manipulation and visualization project: * http://ubietylab.net/ubigraph/ We could write a small test exercising its display capabilities, e.g., the construction of a skeleton on a binary, graph-based image (even a 2-D image on a regular grid). Check the license(s); the client part is Free Software, but the server doesn't seem so. -- Ticket URL: <https://trac.lrde.org/olena/ticket/153> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

#143: Reorganize milena/mln/core/ ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: task | Status: new Priority: minor | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- (This ticket is just a proposal. We might close it even if no change occur in `milena/mln/core`.) There are many things in source:trunk/milena/mln/core/, that could be reorganized and/or split in several directories/subdirectories: * basic/classic images and entites (`mln::image2d`, etc.) * graph-based images and entities (`mln::graph_image`, etc.) * non classic images and associated tools (`mln::rle_image`, etc.) * morphers (`mln::cast_image`, etc.) * internal/core mechanisms (`initialize.hh` etc.) * general tools (`contract.hh`, `inplace.hh`, etc.) * concepts (though they are located in their own directory, `mln/core/concept/`) * implementation/factoring classes (thought most of them are in `mln/core/internal/`) * other entities, that should be moved elsewhere (`mln::h_vec`, etc.) * and so on. To my (Roland) mind, we should: 1. Identify the different kind of files present in `core/`. 2. Assign one (maybe two) kinds to each file of this directory. 3. Determine a new file layout, and perform the moves. -- Ticket URL: <https://trac.lrde.org/olena/ticket/143> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

Note: this can be solved with iterators where the dimension can be either static or dynamic. Let's start with a dynamic one, as it would allow us to write something like this: mln_fwd_citer_(topo::complex<D>) f(c); mln_fwd_lower_nciter(topo::complex<D>) n(c); for_all(c) for_all(n) // ... (Note: we might want to get rid of the name `citer', and use `fiter' everywhere.). A static version might be useful (and more efficient) too. Likewise, our iterators on n-faces (both faces_piter and complex_faces_piter) use a static `n'. We should also have n-faces iterators where n could be dynamic.

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.

#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,,'' ; * ...
