视觉加工通常分为三个阶段-早期，中期和高级视觉，大致对应于视觉世界的感觉，感知和认知。在这篇论文中，我们提出了一个基于网络的中级视觉模型，重点关注表面如何在视觉皮层中表示。我们提出了一种机制，通过建立“所有权”-轮廓和区域的选择性绑定来表示表面。所有权的表征为视觉整合提供了一个中心位置。我们的模拟显示了分割真实的和虚幻的图像的能力与人类的感知一致的方式。此外，通过所有权，其他过程（如深度，透明度和表面完成）可以相互交互，将图像组织成感知场景。
Visual processing has often been divided into three stages-early, intermediate, and high level vision, which roughly correspond to the sensation, perception, and cognition of the visual world. in this paper, we present a network-based model of intermediate-level vision that focuses on how surfaces might be represented in visual cortex. We propose a mechanism for representing surfaces through the establishment of ''ownership''-a selective binding of contours and regions. The representation of ownership provides a central locus for visual integration. Our simulations show the ability to segment real and illusory images in a manner consistent with human perception. In addition, through ownership, other processes such as depth, transparency, and surface completion can interact with one another to organize an image into a perceptual scene.
