 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~\cite{PSECAL07,psnrhvsm11} and the BIQI~\cite{MB10,biqi11}.

+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).
