Figure–ground (perception) Figure–ground organization is a type of perceptual grouping that is a vital necessity for recognizing objects through vision. In Gestalt psychology it is known as identifying a figure from the back ground. For example, black words on a printed paper are seen as the "figure", and the white sheet as the "background ...
Rubin's vase (sometimes known as the Rubin face or the figure–ground vase) is a famous example of ambiguous or bi-stable (i.e., reversing) two-dimensional forms developed around 1915 by the Danish psychologist Edgar Rubin.
Form perception is a demanding task for the brain because a retina has a significant blind spot and retinal veins that obstruct light from reaching cells that detect light, or photoreceptor cells. The brain handles the blind spots through boundary processes, includes perceptual grouping, boundary completion, and figure-ground separation, and ...
Parallelism is another way to disambiguate the figure of an image. The orientation of the contours of different textures in an image can determine which objects are grouped together. Generally, parallel contours suggest membership to the same object or group of objects. Similarly, symmetry of the contours can also define the figure of an image. [6]
A figure-ground diagram is a two-dimensional map of an urban space that shows the relationship between built and unbuilt space. It is used in analysis of urban design and planning. It is akin to but not the same as a Nolli map which denotes public space both within and outside buildings and also akin to a block pattern diagram that records ...
Figure and ground is a concept drawn from Gestalt psychology by media theorist Marshall McLuhan in the early 1970s. This concept underpins the meaning of his famous phrase, "The medium is the message". The concept was an approach to what was called "perceptual organization." He began to use the terms figure and ground as a way "to describe the ...
Like figure-ground organization, perceptual grouping (sometimes called perceptual segregation) [31] is a form of perceptual organization. [16] Perceptual grouping is the process that determines how organisms perceive some parts of their perceptual fields as being more related than others, [16] using such information for object detection.
