For future work, the authors' intention is to investigate systematically
-all the existing edge detection methods, to see if the STABYLO evaluation scores can
-be improved by replacing Canny with another edge filter.

Other steganalysers than the ones used in this document will be
examined for the sake of completeness. Finally, the
