The Olena Team is proud to announce the release of Olena 1.0.

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.

The package also features Swilena, an optional component exposing Milena to other languages thanks to the Simplified Wrapper and Interface Generator (SWIG). For the moment, only some Python bindings are provided.

The Olena platform is Free Software. It is distributed under the conditions of the GNU General Public License (GPL) version 2. See the file COPYING shipped with the Olena distribution.

Here is a list of major changes since Olena 0.11:

* The core C++ library, renamed to Milena, has been rewritten from scratch and features numerous additions over the past releases. Some features have also been dropped or disabled, and some of them will be reintegrated in future releases. The programming interface has changed from previous versions, but most programs using Olena 0.11 can be adapted to the Olena 1.0 API.

* Milena uses a simplified version of the SCOOP 2 paradigm (informally called SCOOP 1.5), to improve the speed of compilation and make developing easier while still providing very good run-time performances.

* A first (re)implementation of Swilena featuring Python wrappers for a very small subset of Milena is available. The bundled Swilena Python Shell (sps) allows interactive Olena sessions.

* A reference documentation including a tutorial and a quick reference guide have been started. They do not cover the whole Milena library yet.

* Olena includes some demos and applications using Milena.
