Hybrid Image
A hybrid image is an image that is visual perception, perceived in one of two different ways, depending on viewing distance, based on the way humans process visual input. A technique for creating hybrid images exhibiting this optical illusion was developed by Aude Oliva of Massachusetts Institute of Technology, MIT and Philippe G. Schyns of University of Glasgow, a method they originally proposed in 1994. Hybrid images combine the low spatial frequencies of one picture with the high spatial frequencies of another picture, producing an image with an interpretation that changes with viewing distance. Perhaps the most familiar example is one featuring Albert Einstein and Marilyn Monroe. Looking at the picture from a short distance, one can see a sharp image of Einstein, with only a hint of blurry distortion hinting at the presence of an overlaid image. Viewed from a distance in which the fine detail blurs, the unmistakable face of Monroe emerges. See also *Optical illusions Re ...

Southeast Hybrid Image Illusion
The points of the compass are a set of horizontal, Radius, radially arrayed compass directions (or Azimuth#In navigation, azimuths) used in navigation and cartography. A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degree (angle), degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and northwest—each located halfway between two cardinal directions. Some disciplines such as meteorology and navigation further divide the compass with additional azimuths. Within European tradition, a fully defined compass has 32 'points' (and any finer subdivisions are described in fractions of points). Compass points are valuable in that they allow a user to refer to a specific azimuth in a Colloquialism, colloquial fashion, without having to compute or remember degrees. Designations The names of the compass point directions follow these rules: 8-wind compass rose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Visual Perception
Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment. This is different from visual acuity, which refers to how clearly a person sees (for example "20/20 vision"). A person can have problems with visual perceptual processing even if they have 20/20 vision. The resulting perception is also known as vision, sight, or eyesight (adjectives ''visual'', ''optical'', and ''ocular'', respectively). The various physiological components involved in vision are referred to collectively as the visual system, and are the focus of much research in linguistics, psychology, cognitive science, neuroscience, and molecular biology, collectively referred to as vision science. Visual system In humans and a number of other mammals, light enters the eye through the cornea and is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Illusion
Within visual perception, an optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual perception, percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation. According to that, there are three main classes: physical, physiological, and cognitive illusions, and in each class there are four kinds: Ambiguities, distortions, paradoxes, and fictions. A classical example for a physical distortion would be the apparent bending of a stick half immerged in water; an example for a physiological paradox is the motion aftereffect (where, despite movement, position remains unchanged). An example for a physiological fiction is an afterimage. Three typical cognitive distortions are the Ponzo illusion, Ponzo, Poggendorff illusion, Poggendorff, an ...

Aude Oliva
Aude Oliva is a French professor of computer vision, neuroscience, and human-computer interaction at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL). Education Oliva has a dual French baccalaureate in mathematics and physics. She then earned a Masters of Science in experimental psychology and cognitive neuroscience from the Institut National Polytechnique in Grenoble and then a doctorate from the same university in 1995. She joined the MIT faculty in 2004 and CSAIL in 2012. Research Oliva's group investigates how psychological perception of an image can change based on memorability, content, and limitations of human visual systems. Her most recognizable work is the hybrid image, the classic example of which combines the high-frequency outline and detail of Albert Einstein's face with a blurry, low-frequency image of Marilyn Monroe; the latter becomes focused only when viewed from long distances. Such images have found use in information privacy, time- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spatial Frequencies
In mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space. The spatial frequency is a measure of how often sinusoidal components (as determined by the Fourier transform) of the structure repeat per unit of distance. The SI unit of spatial frequency is cycles per meter (m). In image-processing applications, spatial frequency is often expressed in units of cycles per millimeter (mm) or equivalently line pairs per mm. In wave propagation, the spatial frequency is also known as ''wavenumber''. Ordinary wavenumber is defined as the reciprocal of wavelength \lambda and is commonly denoted by \xi or sometimes \nu: :\xi = \frac. Angular wavenumber k, expressed in rad per m, is related to ordinary wavenumber and wavelength by :k = 2 \pi \xi = \frac. Visual perception In the study of visual perception, sinusoidal gratings are frequently used to probe the capabilities of the visual system. In these stimu ...

Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Marilyn Monroe
Marilyn Monroe (; born Norma Jeane Mortenson; 1 June 1926 4 August 1962) was an American actress. Famous for playing comedic " blonde bombshell" characters, she became one of the most popular sex symbols of the 1950s and early 1960s, as well as an emblem of the era's sexual revolution. She was a top-billed actress for a decade, and her films grossed $200 million (equivalent to $ billion in ) by the time of her death in 1962. Long after her death, Monroe remains a major icon of pop culture. In 1999, the American Film Institute ranked her sixth on their list of the greatest female screen legends from the Golden Age of Hollywood. Multiple film critics and media outlets have cited Monroe as one of the best actors never to have received an Academy Award nomination. Born and raised in Los Angeles, Monroe spent most of her childhood in a total of 12 foster homes and an orphanage; she married at age sixteen. She was working in a factory during World War II when she met a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
