For Ofeli Publisher's description


Ofeli is a Photo & Image software developed by Fabien Bessy. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Ofeli:

EditByBSEditor: Ofeli (as an acronym for Open, Fast and Efficient Level set Implementation) demonstrates how to operate an image segmentation Algorithm of Y. Shi and W. C. Karl |1|, using a discrete approach for the approximation of level-set-based curve evolution (implicit active contours). This is a novel (2005) and fast algorithm without the need of solving partial differential equations (PDE) while preserving the advantages of level set methods, such as the automatic handling of topological changes. Considerable speedups (×100) have been demonstrated as compared to PDE-based narrow band level-set implementations.


An Image Processing Library written in c++ language with :
*An Abstract implementation of the Y.Shi and W. C. Karl 's Fast-Two-Cycle (FTC) algorithm |1|.
*Inheritance-based implementations with specific speeds derived from Chan-Vese model |2| (region-based) and geodesic model |3| (edge-based) to create an API for a good reusability of the code.
*And more.

A cross-platform (Windows, Mac OS X and GNU/Linux) graphical user interface written in c++/Qt :
*A main window based on Image Viewer example of the Qt documentation to display the input image and each step of the active Contour.
*A settings window to control external speed models, optional internal speed, active contour initialization, preprocessing and image display of the main window with a refresh/interactive view of each modification and a mouse event handling for initialization.
*And more.

A developer's documentation :

*Generated from the source code with Doxygen.
*In french language for the time being.
