Accidental Viewpoint
An accidental viewpoint (i.e. eccentric or fixed viewpoint) is a singular position from which an image can be perceived, creating either an ambiguous image or an illusion. The image perceived at this angle is viewpoint-specific, meaning it cannot be perceived at any other position, known as generic or non-accidental viewpoints. These view-specific angles are involved in object recognition. In its uses in art and other visual illusions, the accidental viewpoint creates the perception of depth often on a two-dimensional surface with the assistance of monocular cues. Object recognition According to the recognition-by-components theory, object recognition is viewpoint-invariant. However, viewpoint specific angles are a necessity in object recognition when identifiable features cannot be viewed from all angles. Object recognition is more accurate when identifying similarities between objects that are moving compared to objects that are static. In this case, viewing an object from a ...

Ambiguous Image
Ambiguous images or reversible figures are visual forms that create ambiguity by exploiting graphical similarities and other properties of visual system interpretation between two or more distinct image forms. These are famous for inducing the phenomenon of multistable perception. Multistable perception is the occurrence of an image being able to provide multiple, although stable, perceptions. One of the earliest examples of this type is the rabbit–duck illusion, first published in ''Fliegende Blätter'', a German humor magazine. Other classic examples are the Rubin vase, and the "My Wife and My Mother-in-Law" drawing, the latter dating from a German postcard of 1888. Ambiguous images are important to the field of psychology because they are often research tools used in experiments. There is varying evidence on whether ambiguous images can be represented mentally, but a majority of research has theorized that mental images cannot be ambiguous. Identifying and resolving ambi ...

Depth Perception
Depth perception is the ability to perceive distance to objects in the world using the visual system and visual perception. It is a major factor in perceiving the world in three dimensions. Depth perception happens primarily due to stereopsis and accommodation of the eye. Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known whether they perceive it in the same way that humans do. Depth perception arises from a variety of depth cues. These are typically classified into binocular cues and monocular cues. Binocular cues are based on the receipt of sensory information in three dimensions from both eyes and monocular cues can be observed with just one eye. Binocular cues include retinal disparity, which exploits parallax and vergence. Stereopsis is made possible with binocular vision. Monocular cues include relative size (distant objects subtend smaller visual angles than near obj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recognition-by-components Theory
The recognition-by-components theory, or RBC theory, is a process proposed by Irving Biederman in 1987 to explain object recognition. According to RBC theory, we are able to recognize objects by separating them into '' geons'' (the object’s main component parts). Biederman suggested that geons are based on basic 3-dimensional shapes (cylinders, cones, etc.) that can be assembled in various arrangements to form a virtually unlimited number of objects. Geons The recognition-by-components theory suggests that there are fewer than 36 geons which are combined to create the objects we see in day-to-day life. For example, when looking at a mug we break it down into two components – "cylinder" and "handle". This also works for more complex objects, which in turn are made up of a larger number of geons. Perceived geons are then compared with objects in our stored memory to identify what it is we are looking at. The theory proposes that when we view objects we look for two important co ...

Anamorphosis
Anamorphosis is a distorted projection requiring the viewer to occupy a specific vantage point, use special devices, or both to view a recognizable image. It is used in painting, photography, sculpture and installation, toys, and film special effects. The word is derived from the Greek prefix ''ana-'', meaning "back" or "again", and the word ''morphe'', meaning "shape" or "form". Extreme anamorphosis has been used by artists to disguise caricatures, erotic and scatological scenes, and other furtive images from a casual spectator, while revealing an undistorted image to the knowledgeable viewer. Types of projection There are two main types of anamorphosis: ''perspective'' (oblique) and ''mirror'' (catoptric). More complex anamorphoses can be devised using distorted lenses, mirrors, or other optical transformations. An oblique anamorphism forms an affine transformation of the subject. Early examples of Perspective (graphical), perspectival anamorphosis date to the Renaissance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean François Niceron
Jean-François Niceron (5 July 1613 – 22 September 1646) was a French mathematician, Minim friar, and painter of anamorphic art, on which he wrote the ground-breaking book ''La Perspective Curieuse'' (Curious Perspectives). Biography Jean-François Niceron was a mathematical prodigy. He studied under Father Marin Mersenne, a famed mathematician and Minim friar, at the College de Nevers. In 1632, at the age of nineteen, he joined the Order of Minims. Niceron was also an artist, with a particular interest in the use of anamorphosis in religious art. He was acquainted with the leading scientists in France and Italy, such as Fermat, Descartes, Cavalieri, and Kircher, and was aware of the latest theoretical developments. Intent on finding a scientific solution to the problems presented by perspective, Niceron worked out the geometric algorithms for producing anamorphic art and in 1638, at the age of 25, published a treatise titled ''La perspective curieuse, ou magie artifi ...

The Ambassadors (Holbein)
''The Ambassadors'' is a 1533 painting by Hans Holbein the Younger. Also known as '' Jean de Dinteville and Georges de Selve'', after the two people it portrays, it was created in the Tudor period, in the same year Elizabeth I was born. Franny Moyle speculates that Elizabeth's mother, Anne Boleyn, then Queen of England, might have commissioned the painting as a gift for Jean de Dinteville, the ambassador portrayed on the left in the painting. As well as being a double portrait, the painting contains a still life of several meticulously rendered objects, the meaning of which is the cause of much debate. It also incorporates one of the best-known examples of anamorphosis in painting. ''The Ambassadors'' has been part of London's National Gallery collection since its purchase in 1890. Description Although a German-born artist who spent much of his time in England, Holbein here displays the influence of Early Netherlandish painting. He used oils which for panel paintings had been dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raree Show
A raree show, peep show or peep box is an exhibition of pictures or objects (or a combination of both), viewed through a small hole or magnifying glass. In 17th and 18th century Europe, it was a popular form of entertainment provided by wandering showmen. History Peep shows, also known as peep box or raree show ("rarity show") can be traced back to the early modern period (15th century in Europe) and are known in various cultures. Around 1437 Italian humanist author, artist, architect, poet, priest, linguist, philosopher and cryptographer Leon Battista Alberti is thought to have created the earliest impressive peep show boxes with painted pictures to be viewed through a small hole. He had two kinds: night scenes with the moon and stars, and day scenes. It is thought these pictures may have been transparent and lit from behind, possibly changing from day to night by changing the lighting. It has also been suggested that it may have been a predecessor of the magic lantern that coul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoogstraten Perspective Box
Hoogstraten () is a municipality located in the Belgian province of Antwerp. The municipality comprises Hoogstraten, Meer, Meerle, Meersel-Dreef, Minderhout and Wortel (Meersel-Dreef includes the northernmost point in Belgium). Hoogstraten (originally ''Hoogstraeten'') has a population of over 20,000, and lies in Flanders at the northern border of Belgium within an enclave surrounded on three sides by the Netherlands. Today, about 15% percent of the population consists of Dutch people. The town is named after the ''hoge straat'' or "high road" – a military highway that linked the old towns of Antwerp and 's-Hertogenbosch. In the town's early days, little trade existed. Villages and towns produced just enough for their own support, with little or no surplus to be 'sold' to other areas. Thus, most travelers along this high road were soldiers and armies. Today Hoogstraten is internationally known for its strawberries. Veiling Hoogstraten (auction) is one of the largest of the B ...
