+\subsection{Image Quality}
+The visual quality of the STABYLO scheme is evaluated in this section.
+Three 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 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.
