物体的视觉感知依赖于作用于零碎输入的分割和分组过程。本文对这些过程进行了简要的概述。描述了一种用于轮廓内插的简单几何学，并考虑了它在2D、3D和时空对象内插过程中的应用。描述了一种用于区分基于该几何的内插与更全局或自上而下的影响的方法。结果表明，基于相对局部刺激关系的内插可以产生精确的边界表示，而涉及从部分信息识别的过程之间存在分离，而部分信息不能。该模型的各个方面--尤其是对虚幻和被遮挡物体的统一处理--引发了人们对视觉本质的质疑。虽然人们通常认为虚幻的物体是被感知的，而被遮挡的物体是被推断的，但我建议研究和理论都汇聚在一起，支持一个更统一的描述。虚幻和遮挡的轮廓和表面不分为真实的、感知的和推断的，但都被表现出来，在关键方面，来自相同的感知过程。
Visual perception of objects depends on segmentation and grouping processes that act on fragmentary input. This paper gives a brief overview of these processes. A simple geometry accounting for contour interpolation is described, and its applications to 2D, 3D, and spatiotemporal object interpolation processes are considered. A method is described for distinguishing interpolation based on this geometry from more global or top-down influences. Results suggest a separation between interpolation based on relatively local stimulus relations, which give rise to precise boundary representations, and processes involving recognition from partial information, which do not. 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 research and theory converge in supporting a more 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 respects, derive from identical perceptual processes.
