Copyright issue
Per the discussion at User talk:Aliud and User talk:Crzrussian, Perceptual transparency and Filling-in were pasted in from an exam paper the author submitted to a university. There is/was some question as to whether the university holds a copyright on this information. -AED 21:49, 18 September 2006 (UTC)

Clarifications
Where the article says: "neither the surface colour, nor the fusion colour in perceived, but only the colour resulting from the fusion of that of the transparent surface and that of the background", shouldn't it say "neither the surface colour, nor the BACKGROUND colour in perceived, but only the colour resulting from the fusion of that of the transparent surface and that of the background" ?

Where it says: "appearance does not reflect the physical model", does physical model'' refer to the physical world setup (ie. filter material on top of some background material), or it refers to a model, in this case the convergence model? In other words, is the sentence trying to say that the model of transparency illusion differs in its predictions from the perceived transparency illusion (ie. a bad model), or that the real/physical world setup differs from what is perceived as the transparency illusion (ie. we fooled the visual system)?

Thanks for the clarifications. —Preceding unsigned comment added by 220.244.111.6 (talk) 13:08, 31 January 2009 (UTC)
