Author description: The primary ‘goal’ of vision is to efficiently identify objects in a scene and organize them into a perceptual 3D space. In real-world scenes, objects occlude other objects in a figure/ground hierarchy, and the visual brain must perceptually complete occluded features. The mechanisms underlying figure-ground segregation and object-completion employ filling-in, leading to some spectacular effects (e.g., illusory contours, Kanizsa triangle). Our illusion is a surprising elaboration: low-contrast, pseudo-random ‘clouds’ are completed across a gap while preserving complex perceptual properties. The visual brain operates on perceptual ‘units’, not just lines and boundaries, extending them as needed to complete the 3D scene.
