#134: Overhaul the generation of the documentation -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: major | Milestone: Olena 1.0ß Component: Milena | Version: 1.0 Keywords: doc | -------------------------+-------------------------------------------------- Changes introduced in r1606 downgraded many features that were present before! In particular, source:trunk/milena/doc/Doxyfile.in has been downgraded from Doxygen version 1.5.2 to Doxygen 1.5.1 (why!?). Let's start again on a sound basis. The best way is probably to reused `Doxyfile.in` from a previous revision (e.g, source:trunk/milena/doc/Doxyfile.in#1476), and add current features (e.g., double documentation generation). -- Ticket URL: <https://trac.lrde.org/olena/ticket/134> 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.

#126: Speed up tests -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: major | Milestone: Olena 1.0ß Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Some tests take a very long time to execute. Main causes are: * input image(s) are too big [[BR]] => they should be reduced (sometimes, testing on `lena.pgm` is just too costly); * the default, non-optimized compilation settings (`-O0 -ggdb`) produces very inefficient code for certain algorithms [[BR]] => we should locally increase the level of optimization (e.g., `-O1` or `-O2`) for these tests, and '''document''' this in `Makefile.am` (explain why we made changes in `CXXFLAGS` for a given test). We might want to make a list of lengthy tests here before solving this ticket. -- Ticket URL: <https://trac.lrde.org/olena/ticket/126> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.

We should reintegrate a part of these features, possibly in two M4 macro packages: * one for Olena, * one for Olena-based projects. -- Ticket URL: <https://trac.lrde.org/olena/ticket/129> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.

Use `gcov` to check which parts of Olena are actually covered (instantiated and checked) by the test suite. 1. Automate with make. 1.

#124: Ensure I/O operations on images holding greater-than-8-bit values are robust w.r.t. endianness ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: task | Status: new Priority: minor | Milestone: Olena 1.0ß Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- This might be difficult to check, since it's platform-dependant. At least, we should check this (with the build farm) on a host with an endianness different than IA-32's or Intel 64's (e.g., a SPARC station). According to http://en.wikipedia.org/wiki/Endianness, * Intel IA-32 (and probably Intel 64 and AMD 64) are little-endian; * Motorola 68k, Sun SPARC and IBM System/370 processors are little- endian; * PowerPC, ARM, DEC Alpha, MIPS, HP PA-RISC and Intel IA-64 processors are bi-endian. -- Ticket URL: <https://trac.lrde.org/olena/ticket/124> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.

#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.

#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.
