Perceptual processes that create objects from fragments

Perception of object depends on a number of interacting information processing tasks. This paper gives a brief overview of processes of contour and object perceptions that overcome fragmentary input and produce representation of objects. A simple geometry accounting for contour interpolation is described, and its application to 2-D, 3-D, and spatiotemporal object interpolation processes is considered. Some aspects of the model -- especially the unified treatment of illusory and occluded objects -- raise questions about the nature of seeing. Although it is often believed that illusory objects are perceived, while occluded objects are inferred, I suggest that both the representational theory of mind and the result of research converge in supporting the unified account. Illusory and occluded contours and surfaces do not divide into the real, the perceived, and the inferred, but are all represented, and in key, derive from identical perceptual processes.
