Absrrucr-Perception of objects depends on a number of interacting information processing tasks. This paper gives a brief overview of processes of contour and object perception that overcome fragmentary input and produce representations of objects. A simple geometry accounting for eontour interpolation is described, and its applications to 2-D, 3-D, and spatiotemporal object interpolation processer is considered. Some aspects of the model -especially the unified treatment of illusory and

Although it is often believed that illusory objects are perceived, while occluded objects are infsrred, I suggest that both the rcpresentational theory o f mind and the results of research converge in supporting the unified account. Illusory and occluded cont~urs and surfacer do not divide into the red, the perceived, and the inferred, but are all represented, and in key respects, derive from identical perceptual processes.
