#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.

[Olena] #129: Reintegrate oln.m4 (full or a part of it) into Olena 1.0

#129: Reintegrate oln.m4 (full or a part of it) into Olena 1.0 -----------------------------------+---------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: minor | Milestone: Olena 1.0ß Component: Olena | Version: 1.0 Keywords: configure autoconf M4 | -----------------------------------+---------------------------------------- In Olena 0.11, `oln.m4` (which might be renamed to `olena.m4`) provided useful services to both the Olena package (search for libraries, set up flags for tests, etc.) and autoconfiscated packages using Olena, by providing a `--with-oln` (to be renamed to `--with-olena`) flag. 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.

#132: Use gcov ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: task | Status: new Priority: major | Milestone: Olena 1.0ß Component: Milena | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- 1. Use `gcov` to check which parts of Olena are actually covered (instantiated and checked) by the test suite. 1. Automate with make. 1. Optionally use the LTP GCOV Extension (`lcov`) : http://ltp.sourceforge.net/coverage/lcov.php -- Ticket URL: <https://trac.lrde.org/olena/ticket/132> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image library.

[Olena] #181: Improve the download page

#181: Improve the download page ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: proposal | Status: new Priority: minor | Milestone: Olena 1.0 Component: other | Version: 1.0 Keywords: | ----------------------+----------------------------------------------------- Some Web sites of software projects asks for some (non mandatory) information before proceeding to download. For instance, each download link from the [http://www.itksnap.org/ ITK-SNAP] project redirects to a page similar to this one : http://www.itksnap.org/download/snap/register.php?link=itksnap-1.6.0.1-2008… where the user is invited to give some information (name, company/organization, etc.). The next page offers the user the opportunity to subscribe to one or several of the project's mailing list(s), then starts the download. I (Roland) think this would useful to have something similar on the Olena download page. -- Ticket URL: <https://trac.lrde.org/olena/ticket/181> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

#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.

[Olena] #136: Delegate rgb operators

by Olena

#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.

[Olena] #146: Ensure the output value type is large enough in labeling algorithms

by Olena

#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.

[Olena] #150: Deducing/computing the « complementary » neighborhood

#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.
