Fig. 3From: Survey on computational 3D visual optical art designThe algorithm proposed by Meghrajani and Mazumdar [8] can produce VC with a unique general share. By superimposing the common share (\({S}_{c}\)) and other shares (\({S}_{1}\),\({S}_{2}\)), the user can see different secret images (\({S}_{{S}_{1}}\),\({S}_{{S}_{2}}\))Back to article page
