The Olena Image Processing Platform

Olena is a platform dedicated to image processing and pattern recognition. Its core component is a generic and efficient C++ library called Milena. Milena provides a framework to implement simple, fast, safe, reusable and extensible image processing tool chains. The library provides many ready-to-use image data structures (regular 1D, 2D, 3D images, graph-based images, etc.) and algorithms. Milena's algorithms are built upon classical entities from the image processing field (images, points/sites, domains, neighborhoods, etc.). This design allows image processing developers and practitioners to easily understand, modify, develop and extend new algorithms while retaining the core traits of Milena: genericity and efficiency.

On top of Milena, the Olena platform also features optional modules such as Swilena, a component exposing Milena to other languages thanks to the Simplified Wrapper and Interface Generator (SWIG); and the SCRIBO module for Document Image Analysis.

The Olena platform is Free Software. It is distributed under the conditions of the GNU General Public License (GPL) version 2.

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.
