立体图中的哪些特征定义了导致立体深度的差异？通常的答案是，来自两只眼睛的亮度定义的边缘是匹配的，并产生深度感知1，2。但物体的某些部分可能被其他物体遮挡，从一只眼睛的视野中消失。有人认为，不成对的单眼元素可能在深度上发出遮挡信号，与不匹配元素相关的对深度的定性知觉已被证明与遮挡3-5的几何形状一致。我们设计了一个立体图，模拟粘贴在白色背景上的一个大的黑色矩形前面的一个细节。调整遮挡器的位置，使其左侧边缘遮挡右眼视图中黑色矩形的左侧边缘，使其右侧边缘遮挡左眼视图中黑色矩形的右侧边缘。我们在这里报告，即使没有匹配的双目对应的亮度边缘，也可以从这个立体图中看到定量的立体视觉。
WHAT features in a stereogram define the disparities that lead to stereoscopic depth? The usual answer is that luminance-defined edges from the two eyes are matched and produce depth perception1,2. But parts of an object may be occluded by other objects and absent from one eye's view. It was suggested that unpaired monocular elements might signal occlusion in depth, and the qualitative perception of depth associated with unmatched elements has been shown to be consistent with the geometry of occlusion3–5. We designed a stereogram that simulates a particular in front of a large black rectangle pasted on a white background. The position of the occluder is adjusted so that its left edge obscures the left-hand edge of the black rectangle in the right eye view and its right edge obscures the right-hand edge of the black rectangle in the left eye view. We report here that quantitative stereopsis can be seen from this stereogram, even though there are no binocular corresponding luminance edges to match.
