Béla Julesz
Béla Julesz (also Bela Julesz in English; February 19, 1928 – December 31, 2003) was a Hungarian-born American visual neuroscientist and experimental psychologist in the fields of visual and auditory perception. Julesz was the originator of random dot stereograms which led to the creation of autostereograms. He also was the first to study texture discrimination by constraining second-order statistics. Biography Béla Julesz was born in Budapest, Hungary, on February 19, 1928. He graduated from Budapest University of Technology and Economics in 1950. He started his electrical engineering career at the Telecommunications Research Institute. He immigrated to the United States with his wife Margit after receiving his Ph.D. from the Hungarian Academy of Sciences in 1956. The topic of his doctoral thesis was the theory of microwave systems and television signals. In 1956, Julesz joined the renowned Bell Telephone Laboratories, Incorporated, where he headed the Sensory and Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stereoscope
A stereoscope is a device for viewing a stereoscopy, stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image. A typical stereoscope provides each eye with a lens that makes the image seen through it appear larger and more distant and usually also shifts its apparent horizontal position, so that for a person with normal binocular depth perception the edges of the two images seemingly fuse into one "stereo window". In current practice, the images are prepared so that the scene appears to be beyond this virtual window, through which objects are sometimes allowed to protrude, but this was not always the custom. A divider or other view-limiting feature is usually provided to prevent each eye from being distracted by also seeing the image intended for the other eye. Most people can, with practice and some effort, view stereoscopic image pairs in 3D without the aid of a stereoscope, but the physiological dept ...

Attention
Attention or focus, is the concentration of awareness on some phenomenon to the exclusion of other stimuli. It is the selective concentration on discrete information, either subjectively or objectively. William James (1890) wrote that "Attention is the taking possession by the mind, in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought. Focalization, concentration, of consciousness are of its essence." Attention has also been described as the allocation of limited cognitive processing resources. Attention is manifested by an attentional bottleneck, in terms of the amount of data the brain can process each second; for example, in human vision, less than 1% of the visual input data stream of 1MByte/sec can enter the bottleneck, leading to inattentional blindness. Attention remains a crucial area of investigation within education, psychology, neuroscience, cognitive neuroscience, and neuropsychology. Areas of activ ...

Binocular Vision
Binocular vision is seeing with two eyes. The Field_of_view, field of view that can be surveyed with two eyes is greater than with one eye. To the extent that the visual fields of the two eyes overlap, #Depth, binocular depth can be perceived. This allows objects to be recognized more quickly, camouflage to be detected, spatial relationships to be perceived more quickly and accurately (#Stereopsis, stereopsis) and perception to be less susceptible to optical illusions, optical illusions. In secion #Medical, Medical attention is paid to the occurrence, defects and sharpness of binocular vision. In section #Biological, Biological the occurrence of binocular vision in animals is described.

Motion (physics)
In physics, motion is when an object changes its position with respect to a reference point in a given time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and frame of reference to an observer, measuring the change in position of the body relative to that frame with a change in time. The branch of physics describing the motion of objects without reference to their cause is called ''kinematics'', while the branch studying forces and their effect on motion is called '' dynamics''. If an object is not in motion relative to a given frame of reference, it is said to be ''at rest'', ''motionless'', ''immobile'', '' stationary'', or to have a constant or time-invariant position with reference to its surroundings. Modern physics holds that, as there is no absolute frame of reference, Isaac Newton's concept of '' absolute motion'' cannot be determined. Everything in the universe can be considered to be in motion. Motion applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Piscataway, New Jersey
Piscataway ( ) is a Township (New Jersey), township in Middlesex County, New Jersey, Middlesex County, in the U.S. state of New Jersey. It is a suburb of the New York metropolitan area, in the Raritan River, Raritan Valley. As of the 2020 United States census, the township's population was 60,804, an increase of 4,760 (+8.5%) from the 2010 United States census, 2010 census count of 56,044, which in turn reflected an increase of 5,562 (+11.0%) from 50,482 at the 2000 United States census, 2000 census. The name may be derived from the area's earliest European settlers who came from near the Piscataqua River, a landmark defining the coastal border between New Hampshire and Maine, whose name derives from (branch) and (tidal river), or alternatively from (meaning "dark night") and ("place of") or from a Lenape language word meaning "great deer". The area was appropriated in 1666 by Quakers and Baptists who had left the Puritan colony in New Hampshire.Cheslow, Jerry"If You're Think ...

Rutgers University
Rutgers University ( ), officially Rutgers, The State University of New Jersey, is a Public university, public land-grant research university consisting of three campuses in New Jersey. Chartered in 1766, Rutgers was originally called Queen's College and was affiliated with the Reformed Church in America, Dutch Reformed Church. It is the eighth-oldest college in the United States, the second-oldest in New Jersey (after Princeton University), and one of nine colonial colleges that were chartered before the American Revolution.Stoeckel, Althea"Presidents, professors, and politics: the colonial colleges and the American revolution", ''Conspectus of History'' (1976) 1(3):45–56. In 1825, Queen's College was renamed Rutgers College in honor of Colonel Henry Rutgers, whose substantial gift to the school had stabilized its finances during a period of uncertainty. For most of its existence, Rutgers was a Private university, private liberal arts college. It has evolved into a Mixed-sex ...

Psychology
Psychology is the scientific study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both consciousness, conscious and Unconscious mind, unconscious phenomena, and mental processes such as thoughts, feelings, and motivation, motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the Natural science, natural and social sciences. Biological psychologists seek an understanding of the Emergence, emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as Behavioural sciences, behavioral or Cognitive science, cognitive scientists.

Texton
The term ''texton'' was introduced by Béla Julesz in 1981 to describe "the putative units of pre-attentive human texture perception." The term reemerged in the late 1990s and early 2000s to describe vector quantized responses of a linear filter bank In signal processing, a filter bank (or filterbank) is an array of bandpass filters that separates the input signal into multiple components, each one carrying a sub-band of the original signal.

Second-order Stimulus
Motion perception is the process of inferring the speed and direction of elements in a scene based on visual, vestibular and proprioceptive inputs. Although this process appears straightforward to most observers, it has proven to be a difficult problem from a computational perspective, and difficult to explain in terms of neural processing. Motion perception is studied by many disciplines, including psychology (i.e. visual perception), neurology, neurophysiology, engineering, and computer science. Neuropsychology The inability to perceive motion is called akinetopsia and it may be caused by a lesion to cortical area V5 in the extrastriate cortex. Neuropsychological studies of a patient who could not see motion, seeing the world in a series of static "frames" instead, suggested that visual area V5 in humans is homologous to motion processing area V5/MT in primates. First-order motion perception When two or more stimuli are alternatively switched on and off, they can produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
