\subsection{Image Quality}
The visual quality of the STABYLO scheme is evaluated in this section.
-Three metrics are computed in these experiments :
+Four metrics are computed in these experiments :
the Peak Signal to Noise Ratio (PSNR),
-the PSNR-HVS-M~\cite{PSECAL07,psnrhvsm11} and the BIQI~\cite{MB10,biqi11}.
+the PSNR-HVS-M familly~\cite{PSECAL07,psnrhvsm11} ,
+the BIQI~\cite{MB10,biqi11} and
+the weigthed PSNR (wPSNR)~\cite{DBLP:conf/ih/PereiraVMMP01}.
The first one is widely used but does not take into
account Human Visual System (HVS).
-The two last ones have been designed to tackle this problem.
