Western Art - Cornsweet Illusion - An Exponent of Optical Illusion
Cornsweet Illusion - The History Tom Cornsweet, in 1960, founded Cornsweet Illusion.
A form of Optical Illusion, it is also known as Craik-O'Brien-Cornsweet Illusion or Craik-Cornsweet Illusion, as Craik and O'Brien had also worked towards it in the past.
The Concept In Cornsweet Illusion, a small color effect is given, which imparts a contrasting illusionary effect to the large area associated with it.
The effect is called illusionary, because in reality the area is not affected.
For example, a colored square is divided into two sections with the help of a perpendicular, horizontal, or diagonal demarcation of very light color.
When viewed, one section will appear darker in comparison to the other one.
In reality however, both the sections were at the same contrast level.
The main purpose of Visual Illusion, including Cornsweet Illusion is to understand and show the way human eye and brain process visual information.
In Optical Illusion, the brain uses the contours of shapes in order to apply impact to the regions around.
This takes place as the nerve impulses are transmitted through the visual cortex in the brain.
The retina in the eye perceives the images according to the luminance observed.
Therefore, basically, the brain interprets things based on a set of limited parameters, resulting in an illusory effect at time.
Visual Illusions are intentionally framed to bluff the mind.
The Correlations This Illusion is considered quite similar in style to Mach Bands, except for the following two vital differences: oIn Mach Bands, the illusionary effect is limited only to the part close to the intensity gradient.
However, in the Cornsweet Illusion, the defining divisions influence the perception of the total area attached to it.
oIn this Illusion, the area close to the light part of the side appears lighter than the area close to the dark part of the side.
This is just the opposite of the usual contrast effects of Mach Bands.
Application The Cornsweet Illusion is used to in graphic designing and the related applications for creating attractive and appealing visual effects.
The knowledge of this illusion is also helpful in certain illumination-oriented fields, like radiology.
If unaware of the concepts, the specialists may misread the x-ray images.
The Artists Key artists in the area of Cornsweet Illusions, include Giuseppe Arcimboldo (Italian - 1527-93), M.
C.
Escher (Dutch - 1898-1972), Salvador Dali (Spanish - 1904-1989), Marcel Duchamp (French/American - 1887-1968), and Oscar Reutersvärd (Swedish 1915-2002).
