 Introduction to Olena
======================

Olena_, a platform dedicated to image processing.

.. _Olena: http://olena.lrde.epita.fr


Overview
========

Olena is a platform dedicated to image processing.  At the moment it is
mainly composed of a C++ library: Milena.  This library features many
tools to easily perform image processing tasks.  Its main
characteristic is its genericity: it allows to write an algorithm once
and run it over many kinds of images (gray scale, color, 1D, 2D, 3D,
...).

Olena is a project developed by the `EPITA Research and Development
Laboratory (LRDE)`__ since 1997.  We did numerous prototypes and
throwaway experiments before settling into the kind of programming
paradigm which is finally here.

__ http://www.lrde.epita.fr

We do our image processing research using this library, but most
importantly we have gathered (and still do) generic programming
expertise from the library development.

Yet, Olena is an ongoing development project.  Few algorithms or
definitions may change in a near future.  A list of potential changes
is maintained here :
https://olena.lrde.epita.fr/FeaturesSubjectToChange.

Likewise, the documentation does not cover the whole project yet.  In the
`doc/' directory you will find the first draft of a reference
manual.  It includes a quick reference guide and a tutorial.  This is a
good start.  In `milena/tools' and `milena/doc/examples' few sample
programs are available.  Most of them are already used to illustrate
the tutorial.   For the rest, we're afraid you will have to dig the
code or e-mail us.

   Please direct any question or comments to <olena@lrde.epita.fr>, or
<olena-bugs@lrde.epita.fr>.

   Olena also has a web page, located at
<http://olena.lrde.epita.fr>.


Installation
============

To install Olena on your system, create a `build' directory (even
though it is not mandatory) and type in the classical sequence at the
command prompt::

        mkdir build
	cd build
	../configure
	make
	make install (as root)

Note that an installation is specific to the compiler used to install
it.  Indeed, the call to ``../configure`` enables some workarounds
and, consequently, users must compile with the same compiler to avoid
compatibility problems.

Between ``make`` and ``make install``, you may also want to run::

	make check

 ``make check`` will run the test suite to check the whole library.
Running the test suite may require up several hours.


Please read the INSTALL file for more information about building and
installing Olena.


Additional Features
-------------------

Swilena is an optional component of Olena exposing Milena to other
languages thanks to the Simplified Wrapper and Interface Generator
(SWIG_).

.. _SWIG: http://www.swig.org

For the moment, only some Python_ bindings are provided.  They are
disabled by default because they require extra dependencies (SWIG and
Python).

.. _Python: http://www.python.org

To enable the installation of this module use::

       ./configure --enable-swilena

Sample tools are shipped with the tarball. To enable the installation of
these tools use::

       ./configure --enable-tools

Sample applications are shipped with the tarball.  To enable the
installation of these applications use::

       ./configure --enable-apps

Olena ships with Trimesh, a third-party library that we have been
using to manipulate 3D meshes.  Eventually, we will drop Trimesh from
the distribution.  To enable it, use::

       ./configure --enable-trimesh


To read/write TIFF images with Olena, libtiff is required.  If
``configure`` is unable to find libtiff on your system, you can help
it by specifying the base directory of libtiff, e.g.::

       ./configure --with-tiff=/usr/local


To read/write DICOM images with Olena, GDCM is required.  Likewise,
you can tell ``configure`` where to find it by giving its install
prefix, e.g.::

       ./configure --with-gdcm=/usr/local

Olena use Magick++ to read and write images in common formats.  As for
other optional dependencies, you can specify where it is located (if
needed) at configuration time::

       ./configure --with-magickxx=/usr/local/


Layout of the Tarball

The Olena project directory layout is as follows:

build-aux
   Auxiliary tools used by the GNU Build System during ``configure``
   and ``make`` stages.

Requirements
============

Olena has been tested on the following configurations:

===========================  =============================================
System                       Compiler
===========================  =============================================
GNU/Linux on IA-32           g++ (GNU GCC) 3.3, 3.4, 4.0, 4.1, 4.2 and 4.3
GNU/Linux on IA-32           icpc (Intel C/C++ Compiler) 10.1 and 11.0
GNU/Linux on AMD64/Intel 64  g++ (GNU GCC) 4.1
Mac OS X (10.5) on IA-32     g++ (GNU GCC) 4.0.1
===========================  =============================================


According to the wanted features, some dependencies may be required:


To enable I/O with TIFF images, `libtiff`_ must be installed.

.. _libtiff: http://www.libtiff.org/

To enable I/O with GDCM images, `GDCM`_ must be installed.

.. _GDCM: http://sourceforge.net/apps/mediawiki/gdcm/

To support many image formats in Olena's I/O system, `Magick++`_ must
be installed.

.. _Magick++: http://www.imagemagick.org/Magick++/

The Boost Tuple Library from the `Boost`_ Project is needed if you
want to support tuple accumulators.

.. _Boost: http://www.boost.org/

Apart from GDCM, these dependencies are commonly provided by the
package management systems (e.g., Debian's APT, Mac OS X's Mac Ports,
etc.).  We recommend using package managers instead of installing
dependencies by hand.
