+be improved by replacing Canny with another edge filter. We will try
+to take into account the least significant bits too during all the
+stages of the algorithm, hoping by doing so to be more close to the HUGO scores against
+steganalyzers. Other steganalyzers than the ones used in this document will be
+regarded for the sake of completeness. Finally, the
+systematic replacement of all the LSBs of edges by binary digits provided
+by the BBS generator will be investigated, and the consequences of such a
+replacement, in terms of security, will be discussed.
