+  Version   :   
+  Role      :   Test l'extraction d'une ROI dans une image mono ou multi canal, dont les valeurs sont codes en "unsigned char"
+                Les parametres de la ROI ne sont pas obligatoire, tout comme les canaux. Dans ce cas, les valauers par dfaut 
+                de la classe sont utilises
