+\subsection{Image Quality}
+The visual quality of the STABYLO scheme is evaluated in this section.
+Four metrics are computed in these experiments : 
+the Peak Signal to Noise Ratio (PSNR), 
+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 other last ones have been designed to tackle this problem.
