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.
Figure and ground or Figure ground may refer to: . Figure and ground (media), a concept developed by media theorist Marshall McLuhan Figure–ground (perception), referring to humans' ability to separate foreground from background in visual images.
For the last iteration, pixels above are assigned to the foreground class and pixels below the threshold are assigned to the background class. At the end, all the temporary foreground pixels are combined to constitute the final foreground. All the temporary background pixels are combined to become the final background.
Foreground detection is one of the major tasks in the field of computer vision and image processing whose aim is to detect changes in image sequences. Background subtraction is any technique which allows an image's foreground to be extracted for further processing (object recognition etc.).
Models based on this idea have been used to describe various visual perceptual functions, such as the perception of motion, the perception of depth, and figure-ground perception. [16] [17] The "wholly empirical theory of perception" is a related and newer approach that rationalizes visual perception without explicitly invoking Bayesian formalisms.

Visual scene segmentation is a pre-attentive process where stimuli are grouped together into specific objects against a background. [10] Figure and background regions of an image activate different processing centres: figures use the lateral occipital areas (which involve object processing) and background engages dorso-medial areas.

Figure-ground contrast, in the context of map design, is a property of a map in which the map image can be partitioned into a single feature or type of feature that is considered as an object of attention (the figure), with the remainder of the map being relegated to the background, outside the current focus of attention.
