Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment.
In the absence of other visual depth cues, this might be the only perception mechanism available to infer the object's shape. Additionally the direction of motion can reverse due to the existence of multiple 3D visual solutions. Leaning tower illusion
Pathological visual illusions usually occur throughout the visual field, suggesting global excitability or sensitivity alterations. [33] Alternatively visual hallucination is the perception of an external visual stimulus where none exists. [32] Visual hallucinations are often from focal dysfunction and are usually transient.
Persistence of vision is the optical illusion that occurs when the visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye. [1] The illusion has also been described as "retinal persistence", [2] "persistence of impressions", [3] simply "persistence" and other variations ...
Binocular rivalry is a phenomenon of visual perception in which perception alternates between different images presented to each eye. [1] An image demonstrating binocular rivalry. If one views the image with red-cyan 3D glasses, the text will alternate between red and blue. 3D red cyan glasses are recommended to view this image correctly.
The concept of perspective distortion has fascinated artists, architects, and scientists for centuries, evolving alongside the development of visual culture and optical theory. Perspective distortion refers to the manipulation of visual perception through deliberate techniques that create altered or exaggerated views of objects or scenes.
Color vision, a feature of visual perception, is an ability to perceive differences between light composed of different frequencies independently of light intensity. Color perception is a part of the larger visual system and is mediated by a complex process between neurons that begins with differential stimulation of different types of ...
Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. [1] In other words, brightness is the perception elicited by the luminance of a visual target. The perception is not linear to luminance, and relies on the context of the viewing environment (for example, see White's illusion).
