我们表明，早期视力可以使用单眼提示来快速完成部分封闭的对象。当完成的形状与显示屏中的其他形状相似时，视觉搜索易于发现的片段变得困难。相反，当完成的形状与众不同时，搜索难以检测到的片段变得容易。结果表明，通过被闭塞触发的遮挡边缘的去除和相关区域的连接进行完成。我们找不到有关轮廓或表面可见填充的证据，但确实找到了“功能性”填充的证据，以防止构成片段迅速访问。因此，仅是完整的结构，而不是碎片本身 - 作为快速认识的基础。 （c）1998 Elsevier Science Ltd.保留所有权利。
We show that early vision can use monocular cues to rapidly complete partially-occluded objects. Visual search for easily-detected fragments becomes difficult when the completed shape is similar to others in the display; conversely, search for fragments that are difficult to detect becomes easy when the completed shape is distinctive. Results indicate that completion occurs via the occlusion-triggered removal of occlusion edges and linking of associated regions. We fail to find evidence for a visible filling-in of contours or surfaces, but do find evidence for a 'functional' filling-in that prevents the constituent fragments from being rapidly accessed. As such, it is only the completed structures-and not the fragments themselves-that serve as the basis for rapid recognition. (C) 1998 Elsevier Science Ltd. All rights reserved.
