Uncertainty in visual processes predicts geometrical optical illusions
It is proposed in this paper that many geometrical optical illusions, as well as illusory patterns due to motion signals in line drawings, are due to the statistics of visual computations. The interpretation of image patterns is preceded by a step where image features such as lines, intersections of lines, or local image movement must be derived. However, there are many sources of noise or unce...
متن کاملIllusions in the spatial sense of the eye: Geometrical–optical illusions and the neural representation of space
Differences between the geometrical properties of simple configurations and their visual percept are called geometrical-optical illusions. They can be differentiated from illusions in the brightness or color domains, from ambiguous figures and impossible objects, from trompe l'oeil and perspective drawing with perfectly valid views, and from illusory contours. They were discovered independently...
متن کاملModeling Geometrical Mysteries of Cafe Wall illusions
This paper explores the tilt illusion effect in the Café Wall pattern using a classical Gaussian Receptive Field model. In this illusion, the mortar lines are misperceived as diverging or converging rather than horizontal. We examine the capability of a simple bioplausible filtering model to recognize different degrees of tilt effect in the Café Wall illusion based on different characteristics ...
متن کاملJohann Joseph Oppel (1855) on Geometrical–Optical Illusions: A Translation and Commentary
The term geometrical–optical illusions was coined by Johann Joseph Oppel (1815–1894) in 1855 in order to distinguish spatial distortions of size and orientation from the broader illusions of the senses. We present a translation of Oppel’s article and a commentary on the material described in it. Oppel did much more than give a name to a class of visual spatial distortions. He examined a variety...
متن کاملOptical Illusions Essay
! Optical illusions are images that are visually perceived differently than how they actually appear in reality. These images can be very entertaining, but also very deceiving. Optical illusions are caused by either an error with oneʼs visual sense or an error of intellect. This " error of intellect " occurs when the visual senses correctly interprets an image, but the mindʼs imagination, false...
