Three-dimensional Curvature Contrast—Geometric or Brightness Illusion?
Simultaneous contrast effects have been found across a wide range of visual dimensions. We describe a simultaneous contrast effect--three-dimensional curvature contrast--in which the apparent curvature of a surface defined by shading and texture information is influenced by the curvature of a surrounding surface. The effect is strong and easily measurable. We asked whether the effect depends up...
متن کاملExploring a brightness-drag illusion.
A sudden luminance increment on a moving stimulus was perceived significantly along the trajectory, in the direction of motion, from its displayed position. A nonlinear relationship with stimulus speed, for a Fröhlich-like illusion, but not for the luminance-increment illusion, challenges certain models of spatial mislocalisation and argues for different processes underlying the two illusions.
متن کاملGeneration Gap: Illusion or Reality?
Values have very important functions in any society. The significance becomes so clear when a society has been exposed to changes and strengthening social cohesion is viewed as an essential subject. Great changes as the Islamic Revolution and the Imposed War have been happened in Iran during last several decades. In this line, generations can be understood via direct or indirect experience of...
متن کاملCurvature Blindness Illusion
We report a novel illusion--curvature blindness illusion: a wavy line is perceived as a zigzag line. The following are required for this illusion to occur. First, the luminance contrast polarity of the wavy line against the background is reversed at the turning points. Second, the curvature of the wavy line is somewhat low; the right angle is too steep to be perceived as an illusion. This illus...
متن کاملCurvature relations in three-dimensional symmetric axes
Aspects of symmetric axis geometry in three dimensions are discussed. A notion of radius curvature is defined and a relationship between symmetric axis curvature, radius curvature, and boundary curvature is derived.
