- Perceptual_transparency abstract "Perceptual transparency is the phenomenon of seeing one surface behind another.In our everyday life, we often experience the view of objects through transparent surfaces.Physically transparent surfaces allow the transmission of a certain amount of light raysthrough them. Sometimes nearly the totality of rays is transmitted across the surface withoutsignificant changes of direction or chromaticity, as in the case of air; sometimes only light ata certain wavelength is transmitted, as for coloured glass.Perceptually, the problem of transparency is much more challenging: both the light rayscoming from the transparent surface and those coming from the object behind it do reach thesame retinal location, triggering a single sensorial process. The system somehow maps thisinformation onto a perceptual representation of two different objects.Physical transparency was shown to be neither a sufficient nor a necessary condition forperceptual transparency. Fuchs (1923) showed that when a small portion of a transparent surface is observed, neither the surface colour, nor the fusion colour is perceived, but only the colour resulting from the fusion of that of the transparent surface and that of the background. Tudor-Hart (1928) showed it is not possible to perceive transparency in a totallyhomogeneous field. Metzger (1975) showed that patterns of opaque paper can induce theillusion of transparency, in the absence of physical transparency. In order to distinguishperceptual from physical transparency, the former has often been addressed as transparencyillusion.Paradoxically, however, two models developed within a physical context have longdominated the research in the field of perceptual transparency: the episcotister model byMetelli (1970; 1974) and the filter model by Beck et al. (1984).".
