Question à propos de l'utilisation des opérations de type "distance" implémentées dans Milena
by nicolas parmentier 19 Jan '11

19 Jan '11

Bonjour, Dans le cadre de mes recherches, je pense éventuellement utiliser votre libraire "Milena" afin de traiter une série d'images issues de tomographies. Votre librairie semble, en effet, bien appropriée pour les traitements que je souhaite effectuer sur mes données. J'ai cependant un petit souci concernant une opération particulière : l'évaluation de la distance dans une partie de l'image à partir d'un point du domaine. Pourriez vous m'aider sur l'exemple suivant : Soit le domaine binaire : "Domain.png" (annexé en pièce jointe) J'arrive à réaliser le champ de distance "distance_field.png" sans aucun souci grâce à une commande de type : " mln::image2d<int_u8> distance_field = mln::transform::distance_geodesic(Domain, mln::c4(), int_u8(100)); " Par contre je ne vois pas comment je peux obtenir le résultat "distance_from_seed_pt.png". Il s'agit du calcul de champ de distance à partir du point supérieur gauche dans le domaine valide (en noir). Auriez vous une idée de la façon dont je peux procéder afin d'obtenir ce résultat ? Merci de l'aide que vous voudriez bien m'apporter, Bien à vous, N.

Bonjour, Pour l'instant, une implémentation naïve, "relativement" lisible et sans optimisation, est dispo dans un bac à sable : http://www.google.com/codesearch/p?hl=fr#IGThQjJ7Cjg/milena/sandbox/garrigu… Elle correspond à l'algo de Monasse et Guichard. > Merci de bien vouloir m’indiquer si cet algorithme est bel et bien inclus.

Bonjour, J'ai lu un rapport comme quoi FLLT (fast level line transform) était ou devrait être intégré à Milena. J'ai téléchargé le code source d'Olena 1.0 et je ne trouve rien qui ressemble à FLLT. Merci de bien vouloir m'indiquer si cet algorithme est bel et bien inclus. Cordialement, David Dubois

Snapshots from BuildBot
by Roland Levillain 04 Jun '10

04 Jun '10

BuildBot has been producing snapshots for a while (long before we switched from Subversion to Git), which were compiled from the main development tree (SVN's trunk at the time), and uploaded here: http://www.lrde.epita.fr/dload/olena/snapshots/ However, now that we use Git, it seemed pointless to keep the same mechanism: each commit in /any/ branch ending in a successful build would produce a tarball overwriting the previous snapshot, whatever branch were used in the production of the later. So I adjusted the lrde-build.sh script used by BuildBot to 1. Filter the branches producing a snapshot after a build successfully completed. Currently, these branches are `master', `next' and `swilena'. Ask me if you want to add more branches to this set. 2. Have snapshot be stored in a subdirectory of the previous URL, e.g. http://www.lrde.epita.fr/dload/olena/snapshots/next/ http://www.lrde.epita.fr/dload/olena/snapshots/swilena/ ... This way BuildBot won't overwrite a snapshot with changes on Scribo with, e.g., a snapshot with changes changes on Swilena. The generated documentation is also stored in the subdirectory, as usual. The names used for the tarballs are a bit lengthy, but this removes any ambiguity as for their content IMHO.

Git Statistics
by Roland Levillain 04 May '10

04 May '10

I now automatically generate some stats from the Olena repository using GitStats [1] (not to be confused with GitStat) every night. They are published here: http://www.lrde.epita.fr/~levill_r/olena/stats/ Currently, only the `master', `next' and `prcs-olena' branches are tracked. These stats are also accessible from the side bar and from the development page [2] of the project's Web site. Notes: [1] http://gitstats.sourceforge.net/ [2] http://olena.lrde.epita.fr/Development

BuildBot's state
by Roland Levillain 04 May '10

04 May '10

Olena's BuildBot is up and running since April 8, 2010. Yesterday we had our first successful automated builds in months since the migration to Git! Two of the build slaves successfully went through configuration, compilation, tests and distchecking for branch `next': https://buildfarm.lrde.org/buildfarm/oln/waterfall?branch=next&reload=none * i486-linux-gnu-gcc-4.1 * i486-linux-gnu-icc-11.0 The other builds have failed for various reasons: 1. powerpc-apple-darwin8-gcc-4.0.1: Host is offline. 2. i486-linux-gnu-gcc-3.3: Compilation failure (to be addressed). 3. i486-linux-gnu-gcc-4.2: Known weird behavior/bug of g++ 4.2. 4. i486-linux-gnu-icc-10.1: Compiler suddenly no longer working (weird). 5. x86-64-linux-gnu-gcc-4.1: Build host in bad condition. Cases #1 and #5 are hardware issues. Problem #2 needs some examination. I know how to work around issue #3. Case #4 is weird: previous builds of `next' never exhibited such a compiler issue. I'll try to fix #2 then #3. And I'll try to diagnose #4. We need to work on #1 and #5 with Geoffroy. Please do not send patches into `next' until we have fixed all builds. TIA. I think we also need to set up more build hosts. For instance, I'd like to have builds * using g++ 4.4 on GNU/Linux * using g++ 4.3 on GNU/Linux * on Cygwin (either using g++ 3.4 or g++ 4.x) * possibly with MinGW * possibly using gcc-snapshot (the future g++ 4.5) * possibly on Mac OS X 10.5 or 10.6

Swilena Instalation problem
by Samuel Félix 01 Apr '10

01 Apr '10

Hi there, I'm trying to install swilena, however I'm facing many problems... After ./configure --enable-swilena... everything seems to be ok.. No dependencies problem (Configure result attached) But during Make... I've got many errors like this one: ---- if -Wall -c++ -python -I../../../milena -MD -MF ".deps/config-wrap.Tcc" -o config-wrap.cc ../../../swilena/config.i; then \ mv -f ".deps/config-wrap.Tcc" ".deps/config-wrap.Pcc";\ else \ rm -f ".deps/config-wrap.Tcc"; exit 1;\ fi --- That error I've mentioned before is related to SWIG field. For some reason, the SWIG and many other fields were blank. After reading the Makefile (/opt/olena-1.0/build/swilena/python/Makefile), I've noticed that It failed to fill some configuration commands... most of them related to python.. I have to fill those blanks by myself: SWIG = swig pyexecdir = /opt/olena-1.0/build/swilena/python/ pythondir = /usr/local/lib/python2.6/ PYTHON = /usr/lib/python2.6/ PYTHONINC = /usr/include/python2.6 After that, I thought the installation was about to finish successfully, but I got this error after "make install": test -z "/usr/local/lib/python2.6/" || /bin/mkdir -p "/usr/local/lib/python2.6/" /usr/bin/install -c -m 644 config.py point2d.py dpoint2d.py box2d.py box2d_piter.py int_u8.py int_u32.py neighb2d.py window2d.py image2d_int.py image2d_int_u8.py dynamic_image2d.py '/usr/local/lib/python2.6/' ../../../build-aux/py-compile: 119: /usr/lib/python2.6/: Permission denied make[3]: ** [install-nodist_pythonPYTHON] Erro 126 make[3]: Saindo do diretório `/opt/olena-1.0/build/swilena/python' make[2]: ** [install-am] Erro 2 make[2]: Saindo do diretório `/opt/olena-1.0/build/swilena/python' make[1]: ** [install-recursive] Erro 1 make[1]: Saindo do diretório `/opt/olena-1.0/build/swilena' make: ** [install-recursive] Erro 1 Yes. I'm root :-) I don't know what is the cause of this permission denied Still, I changed to /opt/olena-1.0/swilena/python and tried to run what swig has created... but... samuel@beaver:/opt/olena-1.0/swilena/python$ python swilena.py Traceback (most recent call last): File "swilena.py", line 24, in <module> import config File "/usr/lib/python2.6/ihooks.py", line 406, in import_module q, tail = self.find_head_package(parent, str(name)) File "/usr/lib/python2.6/ihooks.py", line 449, in find_head_package raise ImportError, "No module named " + qname ImportError: No module named config I checked the generated files and there is no config.py available.. I guess there is something missing in the Makefile... not sure... Anyone can help me out? merci, -- Samuel Félix Computer Science M.Sc.
