#136: Delegate rgb operators ----------------------------------+----------------------------------------- Reporter: garrigues | Owner: Olena Team Type: enhancement | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: vectorial values rgb | ----------------------------------+----------------------------------------- Some operators on rgb values are defined (see source:trunk/milena/mln/value/rgb.hh). FIXME: We should not need to define these operators, thanks to Milena's global operator resolution mechanism based on mln::Object. See what prevent us to use this mechanism. For example : There a no operators defined on int_u values because in source:trunk/milena/mln/value/ops.hh we delegate the operation on int_u and on all Scalar<V> to the equivalent type. We could do the same for vectorial values. it will avoid duplicating metal::vec operators in rgb. We could also introduce an new concept : arithmetic value which by default, use operators of its equiv type. -- Ticket URL: <https://trac.lrde.org/olena/ticket/136> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

#146: Ensure the output value type is large enough in labeling algorithms -------------------------------+-------------------------------------------- Reporter: levill_r | Owner: levill_r Type: defect | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: overflow labeling | -------------------------------+-------------------------------------------- Most labeling algorithm do not check that the output value is large enough to hold the whole set of labels. This is at least the case in * source:trunk/milena/mln/labeling/regional_minima.hh * source:trunk/milena/mln/labeling/regional_maxima.hh * source:trunk/milena/mln/morpho/meyer_wst.hh These algorithms should trigger an error if this happens, even if the output value type is not equipped to detect overflows. -- Ticket URL: <https://trac.lrde.org/olena/ticket/146> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

#150: Deducing/computing the « complementary » neighborhood --------------------------+------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: task | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: connectivity | --------------------------+------------------------------------------------- (Suggested by Aroune.) Some algorithms require two neighborhoods: one for the objects of an image (foreground), and one for the background. Most of the time, the latter can be deduced (or computed) from the former, and ''vice versa'' (there might be some cases where a choice can occur, but we'll leave this aside for the moment). * Write a routine for the simplest cases (regular grids). * Search for a general definition (presumably expressed in the context of complexes) to extend this routine to the complex cases (graph-based domains, etc.) -- Ticket URL: <https://trac.lrde.org/olena/ticket/150> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

#152: Add a debug mode to Milena -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: major | Milestone: Olena 1.0 Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Like the Debug mode of the GNU C++ Library (http://gcc.gnu.org/onlinedocs/libstdc++/manual/spine.html) Milena should provide a debug mode that could be switched on/off with a macro definition. This debug mode should * integrate [source:trunk/milena/mln/core/contract.hh mln/core/contract.hh]'s macros (like `mln_assertion`): * add (and merge with current) dynamic checks where applicable (as in the GNU C++ Library's Debug Mode); * add (and merge with current) static checks where applicable (as in GNU C++ Library's Compile Time Checks); * trigger the debug mode of the GNU C++ Library (http://gcc.gnu.org/onlinedocs/libstdc++/manual/debug_mode.html) where applicable; * trigger Compile Time Checks from the GNU C++ Library (http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt12ch29.html) where applicable; * and possibly: undef `NDEBUG` (`-UNDEBUG`) to ensure C++'s `assert`'s are checked. -- Ticket URL: <https://trac.lrde.org/olena/ticket/152> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #128: Handle carefully tests using X11

#128: Handle carefully tests using X11 ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: defect | Status: new Priority: major | Milestone: Olena 1.0ß Component: Milena | Version: 1.0 Keywords: test | ----------------------+----------------------------------------------------- Some tests require X11 visualization programs such as `display` (from !ImageMagick) or `xv`. This is an issue since * the they might not be installed on the machine; * the host/session on which tests are executed might not run a X11 display. IMHO, we could either 1. move them out of the `check` target (and have them launched by the `check-all`/`check-full` target, or a check-x11 target); or 2. have `configure` check whether the required programs are present, as well as a (usable) X11 session. (Maybe the Vaucanson Team ran into such questions; ask them.) -- Ticket URL: <https://trac.lrde.org/olena/ticket/128> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.

The other ASCII-based Netpbm should be checked as well.

#131: Implement area closing and attribue closing --------------------------------------------------------+------------------- Reporter: levill_r | Owner: Olena Team Type: defect | Status: new Priority: minor | Milestone: Static 1.0 Component: Milena | Version: 1.0 Keywords: completion dual naming routines algorithms | --------------------------------------------------------+------------------- Currently, these files are available: * source:trunk/morpho/mln/opening_area.hh * source:trunk/morpho/mln/opening_attribute.hh but there is no equivalent for closings. Implement them. BTW, these files and their routines are called `opening_area` and `opening_attribute`, which is not elegant. Of course the goal is to put forward the opening term; but IMHO, we should use namespace to do this, not prefixes. Or rename them to `area_opening` and `attribute_opening`, which are much more natural. Anyway, any further discussion on the subject of naming algorithms should be carried on in another ticket. -- Ticket URL: <https://trac.lrde.org/olena/ticket/131> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.
