透明度的感知高度依赖于亮度和感知深度。如果图像区域相对于相邻的图像区域具有中间亮度，并且如果它在另一个区域的前面被感知并且具有提供对象通过该区域可见的信息的边界，则该图像区域被视为透明的。然而，透明度不仅仅是这些必要条件的被动最终产品。如果感知的透明度被触发，一些看似更基本的感知原语，如颜色，轮廓和深度可以从根本上改变。因此，通过对透明度的感知，氖色扩散变得明显，深度变化、立体深度捕获可以被消除，并且否则鲁棒的主观轮廓可以被废除。此外，我们表明，透明度是没有强烈耦合到现实世界中的色彩约束，因为亮度和颜色的组合，这将是不可能出现在现实世界中的场景仍然引起了知觉的透明度。而不是看到的透明度作为一个感知的终点，由看似更原始的过程，我们解释知觉的透明度作为一个“原因”，作为一个“效果”。我们推测，这种相互作用的解剖学基础可能在于皮质前馈连接，保持模块隔离和皮质反馈连接，不。
The perception of transparency is highly dependent on luminance and perceived depth. An image region is seen as transparent if it is of intermediate luminance relative to adjacent image regions, and if it is perceived in front of another region and has a boundary which provides information that an object is visible through this region. Yet, transparency is not just the passive end-product of these required conditions. If perceived transparency is triggered, a number of seemingly more elemental perceptual primitives such as color, contour, and depth can be radically altered. Thus, with the perception of transparency, neon color spreading becomes apparent, depth changes, stereoscopic depth capture can be eliminated, and otherwise robust subjective contours can be abolished. In addition, we show that transparency is not coupled strongly to real-world chromatic constraints since combinations of luminance and color which would be unlikely to arise in real-world scenes still give rise to the perception of transparency.Rather than seeing transparency as a perceptual end-point, determined by seemingly more primitive processes, we interpret perceived transparency as much a 'cause', as an 'effect'. We speculate that the anatomical substrate for such mutual interaction may lie in cortical feed-forward connections which maintain modular segregation and cortical feedback connections which do not.
