[Olena] #188: Implement more windows, neighborhoods, and corresponding iterators for complex-based images

by Olena Trac

#188: Implement more windows, neighborhoods, and corresponding iterators for complex-based images ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: task | Status: new Priority: minor | Milestone: Olena 1.1 Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- This ticket is a sequel to #162. In addition to the neighborhoods, windows, and iterators for complex-based images from #162, implement windows/neighborhoods (and corresponding iterators) returning the following elements (where ''n'' is a (fixed) dimension and ''p'' a psite on an ''n''-face). `complex_cell_window`:: 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 transitively 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''. `complex_boundary_cell_window`:: Likewise, but excluding ''p'' (named « ''p''-hat* » in couprie.08.pami). And maybe: `complex_lower_dims_connected_window`:: the set of ''n''-faces sharing a (''n''-1)-face or (''n''-2)-face etc. (by transitivity) with ''p'' (is it useful?); `complex_higher_dims_connected_window`:: the set of ''n''-faces sharing a (''n''+1)-face or (''n''+2)-face etc. (by transitivity) with ''p'' (is it useful?); * 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); * we could have one or several generic classes, using static or dynamic predicates, to implement those windows and neighborhoods. Note that some of these iterators might implement operators on complexes, see http://en.wikipedia.org/wiki/Simplicial_complex#Closure.2C_star.2C_and_link. Do not forget to update [wiki:Olena/ComplexBasedImages]. -- Ticket URL: <https://trac.lrde.org/olena/ticket/188> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #185: Unify algorithms morpho::skeleton_constrained and topo::breadth_first_thinning

by Olena Trac

#185: Unify algorithms morpho::skeleton_constrained and topo::breadth_first_thinning -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Two (very similar) skeletonization algorithms have been developed: 1. source:trunk/milena/mln/morpho/skeleton_constrained.hh 2. source:trunk/milena/mln/topo/skeleton/breadth_first_thinning.hh The first algorithm is probably a bit more generic, as it takes a priority function as input. It has not been tested on complex-based images (known to be supported by the second algorithm). Unify both algorithm (within `topo/skeleton/`), probably using a canvas. Some elements like the constraint or the priority function should provide default values; the only mandatory arguments should be the input image, the neighborhood and the simplicity function. Do not forget to move/adjust corresponding tests/programs accordingly. -- Ticket URL: <https://trac.lrde.org/olena/ticket/185> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

#138: Factor code between native and BGL-based graph structures ---------------------------------+------------------------------------------ Reporter: levill_r | Owner: Olena Team Type: task | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: boost graphs factor | ---------------------------------+------------------------------------------ This is a continuing work of #123. * Ensure the native and BGL-based graphs offer the same services. * Ensure graph-based images can be built upon any of these categories of graphs. * Milena should provide a uniform interface, whatever the graph engine used (native or BGL-based). * Moreover, `configure` should check for the BGL presence and usability, and disable the BGL-based code when needed (at least in tests, and in compiled tools -- we should install headers, even if the BGL is not present, IMHO). -- Ticket URL: <https://trac.lrde.org/olena/ticket/138> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

#209: Fix copyright headers in documentation ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: defect | Status: new Priority: minor | Milestone: Olena 1.1 Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- LaTeX files in milena/doc/ have the special clause: {{{ As a special exception, you may use this file as part of a free software library without restriction.

Moreover, we might want to consider another license for the documentation, like the GNU FDL or the LPPL (I'm not sure the GPL is suited for documentation).

#169: Lighten the repository -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: minor | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Getting a fresh working copy from the repository takes time, as there are many medium- or big-sized files (images and meshes). We should probably remove some of them, or move them elsewhere. Of course, we should remove most of these files from the distribution as well. -- Ticket URL: <https://trac.lrde.org/olena/ticket/169> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #224: Automatically generate ChangeLog entries

by Olena Trac

#224: Automatically generate ChangeLog entries -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: major | Milestone: Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Instead of documenting changes both in Git messages ''and'' !ChangeLog entries, just rely on the first and generate the latter. Use Jim Meyering's `git-to-changelog` script. * http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob_plain;f=build- aux/gitlog-to-changelog * http://git.savannah.gnu.org/cgit/gnulib.git/plain/build-aux/gitlog-to- changelog We can pick some hints and ideas here: * http://git.savannah.gnu.org/cgit/coreutils.git/plain/HACKING * http://git.savannah.gnu.org/cgit/coreutils.git/plain/Makefile.am * http://cyberelk.net/tim/2009/06/25/generating-changelog-files-from- commit-logs/ I suggest we still 1. Record the !ChangeLog into the repository, so that we can fix it (and keep the fixes!). 1. Keep the date of the last !ChangeLog generation so that we generate only the missing entries next time. There's a additional problem with Olena's repository: we have several !ChangeLogs and the system should be either smart enough to find the right !ChangeLog (!ChangeLogs?) or accept tags/metadata to generate entries at the right place. -- Ticket URL: <https://trac.lrde.org/olena/ticket/224> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.
