Occlusion, transparency, and lightness
The lightness of a visual surface is its perceived achromatic reflectance [Adelson, E. H., (2000). Lightness perception and lightness illusions. In M. Gazzaniga (Ed.), The new cognitive neuroscience (2nd ed.) (pp. 339-351) Berlin: Springer; Gilchrist, A. (1999). Lightness perception. In R. W. F. Keil (Ed.), MIT encyclopedia of cognitive science (pp. 471-472). Cambridge: MIT press]. Lightness ra...
متن کاملTransparency and Occlusion
One of the great computational challenges in recovering scene structure from images arises from the fact that some surfaces in a scene are partially obscured by nearer surfaces or media. Both occluding and transparent surfaces interrupt the projection of more distant surfaces, and may be considered two ends of a continuum. Occluding surfaces completely obscure the surfaces that they occlude, wh...
متن کاملThe perceptual representation of transparency , lightness , and gloss
The adaptive role of vision is to provide information about the behaviorally relevant properties of our visual environment. Our evolutionary success relies on recovering sufficient information about the world to fulfill our biological and reproductive needs while avoiding environmental dangers. The attempt to understand vision as a collection of adaptations to specific computational problems ha...
متن کاملLightness constancy through transparency: internal consistency in layered surface representations
Asymmetric lightness matching was employed to measure how the visual system assigns lightness to surface patches seen through partially-transmissive surfaces. Observers adjusted the luminance of a comparison patch seen through transparency, in order to match the lightness of a standard patch seen in plain view. Plots of matched-to-standard luminance were linear, and their slopes were consistent...
