Christopher Tyler
Christopher William Tyler is a neuroscientist, creator of the autostereogram ("Magic Eye" pictures), and is the Head of the Brain Imaging Center at the Smith-Kettlewell Eye Research Institute He also holds a professorship at City University of London. Biography After earning his PhD from the University of Keele (1970), Tyler became a research fellow at Bell Labs (1974–75), where he worked with Bela Julesz, a vision scientist, psychologist, and MacArthur Fellow. Julesz is well known for his invention of the random dot stereogram, for which he used a computer to create a stereo pair of random-dot images. Although nothing except random dots can be seen in each pair, when people look through a stereoscope so that the left image is viewed only by the left eye and the right image is viewed only by the right eye, they see three-dimensional shapes. After leaving Bell Labs, Tyler took a position at Smith-Kettlewell Institute of Visual Sciences. Tyler's scientific interests are in visu ...

Structure From Motion (psychophysics)
This article is about structure from motion in psychophysics. In visual perception, structure from motion (SFM) refers to how humans recover depth structure from object's motion. The human visual field has an important function: capturing the three-dimensional structures of an object using different kinds of visual cues. SFM is a kind of motion visual cue that uses motion of two-dimensional surfaces to demonstrate three-dimensional objects, and this visual cue works really well even independent of other depth cues. Psychological, especially psychophysical studies have been focused on this topic for decades. Psychophysical studies In a 1953 study on SFM done by Wallach and O'Connell the kinetic depth effect was tested. They found that by turning shadow images of a three dimensional object can be used as a cue to recover the structure of the physical object quite well. Johansson's study conducted in 1973 discovered our ability to perceive human form of walking or dancing simp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucas Cranach The Elder
Lucas Cranach the Elder (german: Lucas Cranach der Ältere ; – 16 October 1553) was a German Renaissance painter and printmaker in woodcut and engraving. He was court painter to the Electors of Saxony for most of his career, and is known for his portraits, both of German princes and those of the leaders of the Protestant Reformation, whose cause he embraced with enthusiasm. He was a close friend of Martin Luther. Cranach also painted religious subjects, first in the Catholic tradition, and later trying to find new ways of conveying Lutheran religious concerns in art. He continued throughout his career to paint nude subjects drawn from mythology and religion. Cranach had a large workshop and many of his works exist in different versions; his son Lucas Cranach the Younger and others continued to create versions of his father's works for decades after his death. He has been considered the most successful German artist of his time. Early life He was born at Kronach in uppe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andrea Mantegna
Andrea Mantegna (, , ; September 13, 1506) was an Italian painter, a student of Roman archeology, and son-in-law of Jacopo Bellini. Like other artists of the time, Mantegna experimented with perspective, e.g. by lowering the horizon in order to create a sense of greater monumentality. His flinty, metallic landscapes and somewhat stony figures give evidence of a fundamentally sculptural approach to painting. He also led a workshop that was the leading producer of prints in Venice before 1500. Biography Youth and education Mantegna was born in Isola di Carturo, Venetian Republic close to Padua (now Italy), second son of a carpenter, Biagio. At the age of 11, he became the apprentice of Paduan painter Francesco Squarcione. Squarcione, whose original profession was tailoring, appears to have had a remarkable enthusiasm for ancient art, and a faculty for acting. Like his famous compatriot Petrarca, Squarcione was an ancient Rome enthusiast: he traveled in Italy, and perhaps a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pisanello
Pisanello (c. 1380/1395c. 1450/1455), born Antonio di Puccio Pisano or Antonio di Puccio da Cereto, also erroneously called Vittore Pisano by Giorgio Vasari, was one of the most distinguished painters of the early Italian Renaissance and Quattrocento. He was acclaimed by poets such as Guarino da Verona and praised by humanists of his time, who compared him to such illustrious names as Cimabue, Phidias and Praxiteles. Pisanello is known for his resplendent frescoes in large murals, elegant portraits, small easel pictures, and many brilliant drawings such as those in the Codex Vallardi (Louvre). He is the most important commemorative portrait medallist in the first half of the 15th century, and he can claim to have originated this important genre. He was employed by the Doge of Venice, the Pope in the Vatican and the courts of Verona, Ferrara, Mantua, Milan, Rimini, and by the King of Naples. He stood in high esteem in the Gonzaga and Este families. Pisanello had many of his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jan Van Eyck
Jan van Eyck ( , ; – July 9, 1441) was a painter active in Bruges who was one of the early innovators of what became known as Early Netherlandish painting, and one of the most significant representatives of Early Northern Renaissance art. According to Vasari and other art historians including Ernst Gombrich, he invented oil painting, Gombrich, The Story of Art, page 240 though most now regard that claim as an oversimplification. The surviving records indicate that he was born around 1380 or 1390, most likely in Maaseik (then Maaseyck, hence his name), Limburg, which is located in present-day Belgium. He took employment in The Hague around 1422, when he was already a master painter with workshop assistants, and was employed as painter and ''valet de chambre'' to John III the Pitiless, ruler of the counties of Holland and Hainaut. After John's death in 1425, he was later appointed as court painter to Philip the Good, Duke of Burgundy, and worked in Lille before moving to B ...

Hockney–Falco Thesis
The Hockney–Falco thesis is a theory of art history, advanced by artist David Hockney and physicist Charles M. Falco. Both claimed that advances in realism and accuracy in the history of Western art since the Renaissance were primarily the result of optical instruments such as the camera obscura, camera lucida, and curved mirrors, rather than solely due to the development of artistic technique and skill. Nineteenth-century artists' use of photography had been well documented. In a 2001 book, ''Secret Knowledge: Rediscovering the Lost Techniques of the Old Masters'', Hockney analyzed the work of the Old Masters and argued that the level of accuracy represented in their work is impossible to create by "eyeballing it". Since then, Hockney and Falco have produced a number of publications on positive evidence of the use of optical aids, and the historical plausibility of such methods. The hypothesis led to a variety of conferences and heated discussions. Setup of the 2001 publicatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudolf Arnheim
Rudolf Arnheim (July 15, 1904 – June 9, 2007) was a German-born writer, art and film theorist, and perceptual psychologist. He learned Gestalt psychology from studying under Max Wertheimer and Wolfgang Köhler at the University of Berlin and applied it to art. His magnum opus was his book ''Art and Visual Perception: A Psychology of the Creative Eye'' (1954). Other major books by Arnheim have included ''Visual Thinking'' (1969), and ''The Power of the Center: A Study of Composition in the Visual Arts'' (1982). ''Art and Visual Perception'' was revised, enlarged and published as a new version in 1974, and it has been translated into fourteen languages. He lived in Germany, Italy, England, and the U.S., where he taught at Sarah Lawrence College, Harvard University, and the University of Michigan. In ''Art and Visual Perception'', he tried to use science to better understand art. In his later book ''Visual Thinking'' (1969), Arnheim critiqued the assumption that language goes be ...

A Bar At The Folies-Bergère
''A Bar at the Folies-Bergère'' (french: Un bar aux Folies Bergère) is a painting by Édouard Manet, considered to be his last major work. It was painted in 1882 and exhibited at the Paris Salon of that year. It depicts a scene in the Folies Bergère nightclub in Paris. The painting originally belonged to the composer Emmanuel Chabrier, a close friend of Manet, and hung over his piano. It is now in the Courtauld Gallery in London. Painting The painting exemplifies Manet's commitment to Realism in its detailed representation of a contemporary scene. Many features have puzzled critics but almost all of them have been shown to have a rationale, and the painting has been the subject of numerous popular and scholarly articles. The central figure stands before a mirror, although critics—accusing Manet of ignorance of perspective and alleging various impossibilities in the painting—have debated this point since the earliest reviews were published. In 2000, however, a photograp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
