Notice

• 25/09/2012:
  The new version is released. It does not require to install any external library (everything is included). Also, minor bugs have been corrected.
• 20/07/2012:
  The code is slightly different from the version used in the papers (different superpixel code, modifications in the optimization, different preprocessing of the data...) to make it work on any images without any required preprocessing from the user. As a consequence, the results may change from the one in the paper and feel free to report the one you prefer. If you notice any problem, bug or a huge drop in performances please send an email to: rf.sne@niluoj.dnamra
