Luminance gradient configuration determines perceived lightness in a simple geometric illusion
Accurate perception of surface reflectance poses a significant computational problem for the visual system. The amount of light reflected by a surface is affected by a combination of factors including the surface's reflectance properties and illumination conditions. The latter are not limited by the strength of the illuminant but also include the relative placement of the light illuminating the...
متن کاملIs lightness induction a pictorial illusion?
Lightness induction, or simultaneous lightness contrast (we prefer the term lightness induction since contrast has another meaning in the visual literature, namely, the relative intensity of the stimulation), was studied for a 3-D object (Adelson's wall of blocks) and its 2-D pictorial representations. A statistically significant lightness induction effect was found only for the pictures but no...
متن کاملLightness constancy: ratio invariance and luminance profile.
The term simultaneous lightness constancy describes the capacity of the visual system to perceive equal reflecting surfaces as having the same lightness despite lying in different illumination fields. In some cases, however, a lightness constancy failure occurs; that is, equal reflecting surfaces appear different in lightness when differently illuminated. An open question is whether the luminan...
متن کاملPerceived Lightness Depends on Perceived Spatial
A change in the perceived spatial position of a surface can change its perceived color from black to white or from white to black. This Anding challenges the widespread view that denies any substantial role of depth perception in the perception of surface lightness (the shade of gray between white and black). Since 1948, when Hans Wallach published his classic experiments in lightness constancy...
متن کاملLightness of Munker-White illusion and Simultaneous-Contrast illusion: Establishing an ordinal lightness relation among minimum and split-frame presentations
3 Lightness illusions help us understand the essential strategies human vision employs to process surface properties. Luminance is the amount of light reaching the eyes from a surface. Lightness, on the other hand, is final perception after the convergence of innate visual mechanisms. Therefore, surfaces with the same luminance may have different perceived lightness. One such example is the Sim...
