Competing theories of partially occluded object perception (amodal completion) emphasize
either relatively local contour relationships or global factors such as symmetry. These …

Computing object boundaries from fragmented image data poses a formidable problem for
the visual system. Contours in the image are typically fragmented due to the prevalence of …

PURPOSE: How do we perceive complete objects from fragmented visual information? We
recently reported evidence for the operation of low-level contour interpolation mechanisms …

Models of contour interpolation have been proposed for illusory contour interpolation but
seldom for interpolation of occluded contours. The identity hypothesis (Kellman & Loukides …

The completion of partly occluded objects appears instantaneous and effortless, but
empirically takes measurable time. The current study investigates how amount of occlusion …

New phenomena and results are reported that implicate a common contour interpolation
mechanism in illusory and occluded (modal and amodal) object completion. In 3 …

We studied interpretations of partly occluded shapes. Models that account for amodal
completion mostly deal with local and global contour characteristics. In the current study, we …

Spatial and temporal properties of illusory contours and amodal completion were
investigated using a shape discrimination task. Performance was characterized as accuracy …

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 …

Spatially separated object information can be effortlessly completed in the visual system, as
demonstrated by the well-known Kanizsa-type illusory contours. The perception of illusory …
