Illusory Motion
The term illusory motion, also known as motion illusion, is an optical illusion in which a static image appears to be moving due to the cognition, cognitive effects of interacting color contrasts, object shapes, and position. Beta movement, Apparent motion is the most common type of illusory motion and is perceived when images are displayed in succession at a specific frame rate such as in a movie. The concept was allegedly first identified by Aristotle. Types of illusory motion Induced movement works by moving the background around a fixed object. Films such as ''Airplane!'' and ''Top Secret!'' use a fixed prop and move the background props to give the effect of induced motion. Motion aftereffect occurs when one views moving stimuli for an extended period of time and then focus on a stationary object. The object will appear to move in the opposite direction of the moving stimuli. Mechanics of illusory motion perception Illusory motion is perceived as movement in a number of ...

Optical Art
Op art, short for optical art, is a style of visual art that uses optical illusions. Op artworks are abstract, with many better-known pieces created in black and white. Typically, they give the viewer the impression of movement, hidden images, flashing and vibrating patterns, or swelling or warping. History The antecedents of op art, in terms of graphic and color effects, can be traced back to Neo-impressionism, Cubism, Futurism, Constructivism and Dada. László Moholy-Nagy produced photographic op art and taught the subject in the Bauhaus. One of his lessons consisted of making his students produce holes in cards and then photographing them. ''Time'' magazine coined the term ''op art'' in 1964, in response to Julian Stanczak's show ''Optical Paintings at the Martha Jackson Gallery'', to mean a form of abstract art (specifically non-objective art) that uses optical illusions. Works now described as "op art" had been produced for several years before ''Time's'' 1964 arti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akiyoshi Kitaoka
is a Professor of Psychology at the College of Letters, Ritsumeikan University, Kyoto, Japan. In 1984, he received a BSc from the Department of Biology, University of Tsukuba, Tsukuba, Japan, where he studied animal psychology (burrowing behavior in rats) and (at the Tokyo Metropolitan Institute for Neuroscience) neuronal activity of the inferotemporal cortex in macaque monkeys. After his 1991 PhD from the Institute of Psychology, University of Tsukuba, he specialized in visual perception and visual illusions of geometrical shape, brightness, color, in motion illusions and other visual phenomena like Gestalt completion and Perceptual transparency, based on a modern conception of Gestalt Psychology. He became renowned through his ''Rotating Snakes'' peripheral drift illusion (see above). In 2006, he received the Gold Prize of the 9th L'ORÉAL Art and Science of Color contest. In 2007, he received the Award for Original Studies from the Japanese Society of Cognitive Psychology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merriweather Post Pavilion (album)
''Merriweather Post Pavilion'' is the eighth studio album by American experimental pop group Animal Collective, released in January 2009 on Domino Records. The group recorded the album as a trio featuring members Panda Bear (Noah Lennox), Avey Tare (Dave Portner) and Geologist (Brian Weitz), with co-production by Ben H. Allen. It is titled after the Maryland venue of the same name, where Portner and Weitz attended concerts in their youth. ''Merriweather Post Pavilion'' saw the band continue to explore the electronica-based sound of their previous album ''Strawberry Jam'', but favours a lusher, multi-layered production style compared than its predecessor. Drawing sonically from Panda Bear's 2007 solo album ''Person Pitch'', and working largely without guitars, the band made extensive use of samplers and synthesizers as primary instruments, as well as prominent reverb. The band also installed PA systems in the studio in an attempt to replicate the energy of their live shows. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Collective
Animal Collective is an American experimental pop band formed in Baltimore, Maryland. Its members consist of Avey Tare (David Portner), Panda Bear (Noah Lennox), Geologist (Brian Weitz), and Deakin (Josh Dibb). The band's work is characterized by an eclectic exploration of styles, including psychedelia, freak folk, noise, and electronica, with the use of elements such as loops, drones, sampling, vocal harmonies, and sound collage, alongside complex production techniques. AllMusic's Fred Thomas suggests that the group "defined the face of independent experimental rock during the 2000s and 2010s." Records released under the name "Animal Collective" may include contributions from any or all of its members. Evolving from early collaborations between Lennox and Portner, the collective was not officially established until all four members came together for the album ''Here Comes the Indian'' (2003). Most prior collaborations between the band members were then retroactively classi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neo-psychedelia
Neo-psychedelia is a diverse genre of psychedelic music that draws inspiration from the sounds of 1960s psychedelia, either updating or copying the approaches from that era. Originating in the 1970s, it has occasionally seen mainstream pop success but is typically explored within alternative rock scenes. It initially developed as an outgrowth of the British post-punk scene, where it was also known as acid punk. After post-punk, neo-psychedelia flourished into a more widespread and international movement of artists who applied the spirit of psychedelic rock to new sounds and techniques. Neo-psychedelia may also include forays into psychedelic pop, jangly guitar rock, heavily distorted free-form jams, or recording experiments. A wave of British alternative rock in the 1980s spawned the subgenres dream pop and shoegazing. Characteristics Neo-psychedelic acts borrowed a variety of elements from 1960s psychedelic music. Some emulated the psychedelic pop of bands like the Beat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subjectivity
Subjectivity in a philosophical context has to do with a lack of objective reality. Subjectivity has been given various and ambiguous definitions by differing sources as it is not often the focal point of philosophical discourse.Bykova, Marina F. (February 2018). "On the Problem of Subjectivity: Editor's Introduction". ''Russian Studies in Philosophy''. 56: 1-5 - via EBSCOhost. However, it is related to ideas of consciousness, agency, personhood, philosophy of mind, reality, and truth. Three common definitions include that subjectivity is the quality or condition of: * Something being a '' subject'', narrowly meaning an individual who possesses conscious experiences, such as perspectives, feelings, beliefs, and desires. Solomon, Robert C. "Subjectivity," in Honderich, Ted. ''Oxford Companion to Philosophy (Oxford University Press, 2005), p.900. * Something being a ''subject'', broadly meaning an entity that has agency, meaning that it acts upon or wields power over some other en ...

Aliasing
In signal processing and related disciplines, aliasing is an effect that causes different signals to become indistinguishable (or ''aliases'' of one another) when sampled. It also often refers to the distortion or artifact that results when a signal reconstructed from samples is different from the original continuous signal. Aliasing can occur in signals sampled in time, for instance digital audio, or the stroboscopic effect, and is referred to as temporal aliasing. It can also occur in spatially sampled signals (e.g. moiré patterns in digital images); this type of aliasing is called spatial aliasing. Aliasing is generally avoided by applying low-pass filters or anti-aliasing filters (AAF) to the input signal before sampling and when converting a signal from a higher to a lower sampling rate. Suitable reconstruction filtering should then be used when restoring the sampled signal to the continuous domain or converting a signal from a lower to a higher sampling rate. For spa ...

Counter-rotation
Rotation, or spin, is the circular movement of an object around a '' central axis''. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional object has an infinite number of possible central axes and rotational directions. If the rotation axis passes internally through the body's own center of mass, then the body is said to be ''autorotating'' or ''spinning'', and the surface intersection of the axis can be called a ''pole''. A rotation around a completely external axis, e.g. the planet Earth around the Sun, is called ''revolving'' or ''orbiting'', typically when it is produced by gravity, and the ends of the rotation axis can be called the ''orbital poles''. Mathematics Mathematically, a rotation is a rigid body movement which, unlike a translation, keeps a point fixed. This definition applies to rotations within both two and three dimensions (in a plane and in space, r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Flow
Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and a scene. Optical flow can also be defined as the distribution of apparent velocities of movement of brightness pattern in an image. The concept of optical flow was introduced by the American psychologist James J. Gibson in the 1940s to describe the visual stimulus provided to animals moving through the world. Gibson stressed the importance of optic flow for affordance perception, the ability to discern possibilities for action within the environment. Followers of Gibson and his ecological approach to psychology have further demonstrated the role of the optical flow stimulus for the perception of movement by the observer in the world; perception of the shape, distance and movement of objects in the world; and the control of locomotion. The term optical flow is also used by roboticists, encompassing related techniq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motion Picture
A film also called a movie, motion picture, moving picture, picture, photoplay or (slang) flick is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it. Recording and transmission of film The moving images of a film are created by photography, photographing actual scenes with a movie camera, motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of computer-generated imagery, CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects.
