Illusory motion can occur in different circumstances. Stroboscopic images is where a series of static images are viewed in sequence at a high enough rate that the static images appear to blend into a continuous motion. An example of this is a motion picture.
Illusory contours provide clues for how the visual system constructs surfaces when portions of the surface's edge are not visible. The encoding of surfaces is thought to be an indispensable part of visual perception, forming a critical intermediate stage of visual processing between the initial analysis of visual features and the ability to ...
The Leaning tower illusion is an optical illusion that presents two identical images of the Leaning Tower of Pisa side by side. Lilac chaser: Lilac chaser is a visual illusion, also known as the Pac-Man illusion. Liquid crystal shutter glasses: Lunar terminator illusion
Optical illusion is also used in film by the technique of forced perspective. Op art is a style of art that uses optical illusions to create an impression of movement, or hidden images and patterns. Trompe-l'œil uses realistic imagery to create the optical illusion that depicted objects exist in three dimensions.
In ambiguous images, an illusion is often produced from illusory contours. An illusory contour is a perceived contour without the presence of a physical gradient.
This is an example of a wallpaper with repeated horizontal patterns. Each pattern is repeated exactly every 140 pixels. The illusion of the pictures lying on a flat surface (a plane) further back is created by the brain. Non-repeating patterns such as arrows and words, on the other hand, appear on the plane where this text lies.
In vision, images can be combined through a lapse in memory of an image that is filled by physical stimuli. [8] Illusory conjunctions often occur through memory errors because the situations in which illusory conjunctions happen involve multiple tasks or tasks that commonly divide a person's attention. [9]
The toy has traditionally been thought to demonstrate the principle of persistence of vision, a disputed explanation for the cause of illusory motion in stroboscopic animation and film. Examples of common thaumatrope pictures include a bare tree on one side of the disk, and its leaves on the other, or a bird on one side and a cage on the other.
