This section aims at justifying the lightweight attribute of our approach.
-To be more precise, we compare the complexity of our schemes to the
- best available steganographic scheme, namely HUGO~\cite{DBLP:conf/ih/PevnyFB10}.
+To be more precise, we compare the complexity of our schemes to some of
+current state of the art of
+steganographic scheme, namely HUGO~\cite{DBLP:conf/ih/PevnyFB10},
+WOW~\cite{conf/wifs/HolubF12}, and UNIWARD~\cite{HFD14}.
In what follows, we consider a $n \times n$ square image.
