Mach bands is an optical illusion named after the physicist Ernst Mach. It exaggerates the contrast between edges of the slightly differing shades of gray, as soon as they contact one another, by triggering edge-detection in the human visual system.

2024年3月31日 · Mach bands or the Mach effect refers to an optical phenomenon from edge enhancement due to lateral inhibition of the retina 2. This is an inbuilt edge enhancement mechanism of the retina, where the edges of darker objects next to lighter objects will appear darker and vice versa, creating a false shadow 4 .

Mach bands are an optical illusion where a band of gradients will appear in places to be lighter or darker than they actually are. Mach bands, as well as numerous other visual and perceptual illusions, provide a valuable way to investigate how the eye and brain process visual information.

2014年11月3日 · Mach bands are the illusory dark and bright bars seen at the foot and knee of a luminance trapezoid. First demonstrated by Ernst Mach in the latter part of the 19th century, Mach bands are a test bed not only for models of brightness illusions but of spatial vision in general.

Lateral inhibition explains a famous visual illusion known as Mach bands, named after their discoverer, Physicist Ernst Mach (1838–1916). Lateral inhibition accentuates the edges of the stimulus.

2024年8月6日 · This article explores the Mach Band effect, its causes, implications for image processing, and methods to address it. What is the Mach Band Effect? The Mach Band effect is an optical illusion where the human eye perceives exaggerated contrast at the boundaries between areas of different luminance.

2023年1月1日 · Mach bands are brightness illusions, originally referring to a situation where a lighter and a darker sharp-edged gray area are separated from each other by a gray area where the brightness transforms uniformly from the brighter to the darker field.

1999年4月4日 · Our explanation of Mach bands simply carries this theory of vision into a related domain of brightness perception in which the stimuli are luminance gradients rather than contrasting territories.

Mach bands are brightness illusions, originally referring to a situation where a lighter and a darker sharp-edged gray area are separated from each other by a gray area where the bright-ness transforms uniformly from the brighter to the darker field.

2013年4月7日 · mach bands By N., Sam M.S. is an visual phenomena during which there is a visible contrast produced by two or more adjacent rectangular grey images which differ in lightness.
