Figure–ground (perception) - Wikipedia
Figure–ground organization is a type of perceptual grouping which is a vital necessity for Figure–ground reversal may be used as an intentional visual design technique in which an existing image's foreground and background colors are.

This perceptual decision can be based on many cues, all of which are of a probabilistic nature. For instance, size helps us distinguish between the figure and the ground, since smaller regions are often but not always figures. Object shape can help us distinguish figure from ground, because figures tend to be convex.
Movement also helps; the figure may be moving against a static environment.

Color is also a cue, because the background tends to continue as one color behind potentially multiple foreground figures, whose colors may vary. Edge assignment also helps; if the edge belongs to the figure, it defines the shape while the background exists behind the shape.
But it's at times difficult to distinguish between the two because the edge that would separate figure from ground is really part of neither, it equally defines both the figure and the background.
In this light, Bayesian figure—ground segmentation models have been proposed to simulate the probabilistic inference by which the brain may distinguish figure from ground. Figure—ground reversal may be used as an intentional visual design technique in which an existing image's foreground and background colors are purposely swapped to create new images.

Non-visual[ edit ] Figure—ground perception can be expanded from visual perception to include abstract i. Remember that a positive shape is one that is distinguished from the background.
What about the dark figure standing in the doorway? Here the dark shape becomes the positive one, surrounded by a white background. In three dimensions, positive shapes are those that make up the actual work. The negative shapes are the empty spaces around, and sometimes permeating through the work itself. The Laocoon is a good example of this.
In an abstract style the artist weaves positive and negative shapes together, the result is a dreamy, floating sensation radiating from the sculpture. Plane A plane is defined as any surface area in space. In two-dimensional art, the picture plane is the flat surface an image is created upon; a piece of paper, stretched canvas, wood panel, etc.
The graphic below shows three examples.

Chris Gildow, 'Implied Planes on a 2-dimensional Surface' Traditionally the picture plane has been likened to a window the viewer looks through to a scene beyond, the artist constructing a believable image showing implied depth and planar relationships. Breughel shows us an idyllic landscape with farmers tilling their fields, each terraced row a different plane of earth, and shepherds tending their flocks of sheep in the foreground.
We look further to see a gradual recession to the sea and a middle ground dominated by a ship under sail. The curves of the billowing sails imply two or three different planes.
The background of the painting shows the illusion of deep space, the massive cliffs now small in relation to the foreground, and the distant ship near the center as smaller and lighter in tone. In the grandeur of the scene Icarus falls into the sea unnoticed just off shore to the lower right, only his legs still above water. We will look at the element of space just ahead.
