The elevator illusion results from the combination of body orientation and egocentric perception.

12 Aug 2009 Perception of body orientation and apparent location of objects are altered when humans are using assisted means of locomotion and the resultant of the imposed acceleration and gravity is no longer aligned with the gravitational vertical. As the ... Read more...

The Anderson-Winawer illusion: it's not occlusion.

30 Jul 2009 In their recent article, Anderson and Winawer (2005) presented a dramatic lightness illusion in which identical texture patches appear to be either black or white. Albert (2007) argued that the Anderson and Winawer (2005) illusion can be explained ... Read more...

Saliency on a natural scene background: effects of color and luminance contrast add linearly.

30 Jul 2009 In natural vision, shifts in spatial attention are associated with shifts of gaze. Computational models of such overt attention typically use the concept of a saliency map: Normalized maps of center-surround differences are computed for individual ... Read more...
