The Hollow-Face illusion is an optical illusion in which the perception of a concave mask of a face appears as a normal convex face. Hybrid image. A Hybrid image is an optical illusion developed at MIT in which an image can be interpreted in one of two different ways depending on viewing distance. Illusory contours.
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.
An example of an ambiguous image would be two curving lines intersecting at a point. This junction would be perceived the same way as the "X", where the intersection is seen as the lines crossing rather than turning away from each other. Illusions of good continuation are often used by magicians to trick audiences. Similarity
Lines Across Maps are a British math rock band based in Lincolnshire, England. Their music is characterized by a use of complex time signatures [1] and heavy, guitar driven sounds. [2] In December 2011, shortly after the release of their debut EP, Stuart Smith of This Town Needs Guns described the band as "a lot like Colour (now defunct UK math ...
Two sets of arrows that exhibit the Müller-Lyer optical illusion. The set on the bottom represents the classic Müller-Lyer stimulus, while on the top is its Brentano modification. All the shafts of the arrows are of the same physical length. The Müller-Lyer illusion is an optical illusion consisting of three stylized arrows. When viewers are ...
v. t. e. In technical drawing and computer graphics, a multiview projection is a technique of illustration by which a standardized series of orthographic two-dimensional pictures are constructed to represent the form of a three-dimensional object. Up to six pictures of an object are produced (called primary views ), with each projection plane ...
An astronomical filter is a telescope accessory consisting of an optical filter used by amateur astronomers to simply improve the details and contrast of celestial objects, either for viewing or for photography. Research astronomers, on the other hand, use various band-pass filters for photometry on telescopes, in order to obtain measurements ...
Kikuchi lines are patterns of electrons formed by scattering. They pair up to form bands in electron diffraction from single crystal specimens, there to serve as "roads in orientation-space" for microscopists uncertain of what they are looking at. In transmission electron microscopes, they are easily seen in diffraction from regions of the ...
