#190: Handle Trimesh's dependencies on third-party packages. --------------------------------+------------------------------------------- Reporter: levill_r | Owner: levill_r Type: task | Status: new Priority: minor | Milestone: Olena 1.0 Component: Olena | Version: 1.0 Keywords: Autoconf configure | --------------------------------+------------------------------------------- * OpenGL/Mesa (for Trimesh) * We should check for the presence of `GL/gl.h`, `GL/glu.h` and `libXmu.{a,so}` to enable OpenGL conditionally. * Note: on Debian, Mesa users have to install these packages: * `mesa-common-dev` (for `GL/gl.h`) * `libglu1-mesa-dev` (for `GL/glu.h`) * `libxmu-dev` (for `libXmu.{a,so}`). -- Ticket URL: <https://trac.lrde.org/olena/ticket/190> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #238: Have Swilena be compatible with (also) Python 2.6 (and greater)

by Olena Trac

#238: Have Swilena be compatible with (also) Python 2.6 (and greater) -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: major | Milestone: Component: Swilena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Swilena does not work with Python 2.6 (and probably greater versions). Swig seems to generates wrappers correctly, and they compile fine, but tests fail at run time. There may have been changes in Python's API between versions 2.5 and 2.6 (perhaps iterators?). Investigate. -- Ticket URL: <https://trac.lrde.org/olena/ticket/238> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #160: Revamp complexes

We should get rid of that. We could create an index at the creation of the complex, mapping dynamic dimension numbers to the corresponding (static) mixin/data. Ask Roland for details. -- Ticket URL: <https://trac.lrde.org/olena/ticket/160> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[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.
