Figure–ground (perception)


Figure–ground organization is a type of perceptual grouping which is a vital necessity for recognizing objects through vision. In Gestalt psychology it is known as identifying a figure from the background. For example, you see words on a printed paper as the "figure" and the white sheet as the "background".[1]

There are three types of figure–ground problems:

Type 2: The actual ground is the figure.

Types of figure–ground problems

Figure–ground perception can be expanded from visual perception to include abstract (i.e. non-visual) concepts such as melody/harmony, subject/background and positive/negative space. The concept of figure and ground fully depends on the observer and not on the item itself.[8]


Figure–ground organization is used to help artists and designers in composition of a 2D piece. 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.

Artistic applications

Evidently, the process of distinguishing figure from ground (sometimes called figure–ground segmentation) is inherently probabilistic, and the best that the brain can do is to take all relevant cues into account in order to generate a probabilistic best-guess. 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.[7]

How does the brain decide in a visual scene which item is the figure and which are part of the ground? 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.[6]
