Recent evidence has shown that afterimage perception and completion are amenable to contextual information. It has previously been shown that placing an outline around part of the afterimage can induce colors in areas that were uncolored. A thorough explanation of this effect is lacking, although this color completion was thought to be due to a diffusion-like filling-in of the uncolored patch with colors of the surrounding areas. Here, we show that an important step in visual completion is the decomposition of the visual scene into different depth layers, i.e. scission, which, we show, is guided by transparency cues in the van Lier et al.
In three experiments, we show that when decomposition is prevented, color completion does not occur. We also show that this decomposition can induce color completion in real images. These results demonstrate that transparency information plays an important role in determining visual color completion processes.
最近的证据表明，后像感知和完成受上下文信息的影响。先前的研究表明，在部分后像周围画一个轮廓可以在原本没有颜色的区域中诱导出颜色。尽管这种颜色完成被认为是由于周围区域的颜色扩散式填充到未着色的区域中，但对这种效应还缺乏透彻的解释。在这里，我们表明视觉完成的一个重要步骤是将视觉场景分解成不同的深度层，即分割，我们表明，分割是由 van Lier 等人的透明度线索引导的。
在三个实验中，我们表明，当阻止分解时，颜色完成不会发生。我们还表明，这种分解可以在真实图像中诱导颜色完成。这些结果表明，透明度信息在确定视觉颜色完成过程中起着重要作用。
