Abstract In 1912, Max Wertheimer published his paper on phi motion, widely recognized as
the start of Gestalt psychology. Because of its continued relevance in modern psychology …

Perceptual filling-in occurs when structures of the visual system interpolate information
across regions of visual space where that information is physically absent. It is a ubiquitous …

The problem of amodal perception is the problem of how we represent features of perceived
objects that are occluded or otherwise hidden from us. Bence Nanay (2010) has recently …

Mechanisms of contour completion are critical for computing visual surface structure in the
face of occlusion. Theories of visual completion posit that mechanisms of contour …

One of the main functions of vision is to represent object shape. Most theories of shape
perception focus exclusively on geometrical computations (eg, curvatures, symmetries, axis …

In a well-known magic trick known as multiplying balls, conjurers fool their audience with the
use of a semi-spherical shell, which the audience perceives as a complete ball [1]. Here, we …

Sound sources in the world are experienced as stable even when intermittently obscured,
implying perceptual completion mechanisms that “fill in” missing sensory information. We …

Perception of objects in ordinary scenes requires interpolation processes connecting visible
areas across spatial gaps. Most research has focused on 2-D displays, and models have …

This chapter discusses the phenomena of perceptual completion. First, a historic overview
on the phenomena of amodal and modal completion is given. Next, various approaches and …

A theory is presented that explains how the visual system infers the lightness, opacity, and
depth of surfaces from stereoscopic images. It is shown that the polarity and magnitude of …
