人类视觉感知的一个基本特性是我们区分纹理的能力。一个协调一致的努力已经考虑到纹理分离的线性空间滤波器模型和它们的非线性扩展。然而，对于某些纹理对的歧视的容易程度的变化时，数字和背景的作用是颠倒的。这种不对称性给线性和非线性模型都带来了问题。我们已经分离出一个属性的纹理感知，可以解释这种不对称的歧视：主观封闭。这种特性，也是造成视觉错觉的原因，似乎可以用早期的视觉过程来解释。我们的研究结果迫使重新审查的过程中，人类的纹理隔离和最近的一些模型，介绍了解释它。
A fundamental property of human visual perception is our ability to distinguish between textures. A concerted effort has been made to account for texture segregation in terms of linear spatial filter models and their nonlinear extensions. However, for certain texture pairs the ease of discrimination changes when the role of figure and ground are reversed. This asymmetry poses a problem for both linear and nonlinear models. We have isolated a property of texture perception that can account for this asymmetry in discrimination: subjective closure. This property, which is also responsible for visual illusions, appears to be explainable by early visual processes alone. Our results force a reexamination of the process of human texture segregation and of some recent models that were introduced to explain it.
