Introduction Creaseg
Introduction
This software is a computer program whose purpose is to evaluate the performance of
different level-set based segmentation algorithms in the context of image processing (and more
particularly on biomedical images).
The software has been designed for two main purposes.
• firstly, Creaseg allows you to use six different level-set methods. These methods have
been chosen in order to works with a wide range of level-sets. You can select for instance
classical methods such as Caselles or Chan & Vese level-set, or more recent approaches
such as the one developped by Lankton or Bernard.
• finally, the software allows you to compare the performance of the six level-set methods on
different images. The performance can be evaluated either visually, or from measurements
(e.g. using the Dice coefficient or the PSNR value) between a reference and the results
of the segmentation.
