  2. Visual perception - Wikipedia

    en.wikipedia.org/wiki/Visual_perception

    Models based on this idea have been used to describe various visual perceptual functions, such as the perception of motion, the perception of depth, and figure-ground perception. [16] [17] The "wholly empirical theory of perception" is a related and newer approach that rationalizes visual perception without explicitly invoking Bayesian formalisms.

  3. Optics and vision - Wikipedia

    en.wikipedia.org/wiki/Optics_and_vision

    Visual perception is the ability to interpret information and surroundings from visible light reaching the eye. The resulting perception is also known as eyesight , sight or vision . The various physiological components involved in vision are referred to collectively as the visual system , and are the focus of much research in psychology ...

  4. Visual system - Wikipedia

    en.wikipedia.org/wiki/Visual_system

    The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.

  5. Perception - Wikipedia

    en.wikipedia.org/wiki/Perception

    A perceptual visual event measured in humans was the presentation to individuals of an anomalous word. If these individuals are shown a sentence, presented as a sequence of single words on a computer screen, with a puzzling word out of place in the sequence, the perception of the puzzling word can register on an electroencephalogram (EEG).

  6. Visual processing - Wikipedia

    en.wikipedia.org/wiki/Visual_processing

    The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...

  7. Vision science - Wikipedia

    en.wikipedia.org/wiki/Vision_science

    Vision science encompasses all studies of vision, such as how human and non-human organisms process visual information, how conscious visual perception works in humans, how to exploit visual perception for effective communication, and how artificial systems can do the same tasks.

  8. Emission theory (vision) - Wikipedia

    en.wikipedia.org/wiki/Emission_theory_(vision)

    Emission theory or extramission theory (variants: extromission) or extromissionism is the proposal that visual perception is accomplished by eye beams emitted by the eyes. This theory has been replaced by intromission theory (or intromissionism ), which is that visual perception comes from something representative of the object (later ...

  9. Visual neuroscience - Wikipedia

    en.wikipedia.org/wiki/Visual_neuroscience

    Visual neuroscience is a branch of neuroscience that focuses on the visual system of the human body, mainly located in the brain's visual cortex. The main goal of visual neuroscience is to understand how neural activity results in visual perception , as well as behaviors dependent on vision.
