Optical 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...
متن کاملGeometric-optical illusions at isoluminance
The idea of a largely segregated processing of color and form was initially supported by observations that geometric-optical illusions vanish under isoluminance. However, this finding is inconsistent with some psychophysical studies and also with physiological evidence showing that color and luminance are processed together by largely overlapping sets of neurons in the LGN, in V1, and in extras...
متن کاملModeling geometric-optical illusions: A variational approach
Visual distortions of perceived lengths, angles, or forms, are generally known as “geometric–optical illusions” (GOI). In the present paper we focus on a class of GOIs where the distortion of a straight line segment (the “target” stimulus) is induced by an array of non-intersecting curvilinear elements (“context” stimulus). Assuming local target– context interactions in a vector field represent...
متن کاملGeometric-optical illusions and Riemannian geometry
Geometric-optical illusions (goi) are a subclass of a vast variety of visual illusions. A special class of gois originates from the superposition of a simple geometric figure (“target”) with an array of non-intersecting curvilinear elements (“context”) that elicits a perceptual distortion of the target element. Here we specifically deal with the case of circular targets. Starting from the fact ...
متن کاملAnalysis of Gaze on Optical Illusions
A comparison of human gaze patterns on illusions before and after a simple color manipulation is presented. The optical illusions used include Fraser’s illusion, Akiyoshi Kitaoka’s Rotating Snakes, and the Necker cube. All of these images were then modified in an attempt to render the illusion non-illusory. The images are then shown to 8 participants, split into two groups of 4. Each group will...
