Perception must separate object {figure, Gestalt} from background, using Gestalt laws [Ehrenfels, 1891]. Regions with one color are figures. Many-colored regions are ground. Smaller region is figure, and nearby larger region is ground.
Edges separate figure and ground. Lateral inhibition distinguishes and sharpens boundaries.
Both figure and ground are homogeneous regions. Surfaces recruit neighboring similar surfaces to expand homogeneous regions by wave entrainment.
Vision separates figure and ground by detecting edges and increasing homogeneous regions, using constraint satisfaction [Crane, 1992].
