Olena

Olena is a software 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 (grey scale, color, 1D, 2D, 3D…).

See the Overview of Olena for a longer introduction to the project. French speaking readers can also look at the article introducing Olena 1.0 in L'air de rien 17.

Milena

The C++ library of Olena is Milena. It contains:

• different image types
• many tools to ease programming image processing tasks
• a collection of image processing operators.

Several modules based upon Milena are available from the Modules page. They provide solutions to particular tasks of image processing, whereas the library focuses on general-purpose facilities for image processing. Practically modules are:

• source code related to our publications (we advocate reproducible research!)
• source code of our participation to contests
• source code of projects we are involved with.

Availability

Olena is Free Software. It is released under the conditions of the GNU General Public License version 2.

See the Download page to get the package.
