自然环境包含由边定义的平滑曲面,这些边定义一个对象或曲面的终点和另一个对象或曲面的起点。许多实验表明,人类视觉系统擅长使用单一的深度提示来对这些曲面进行插补,即立体视觉。然而,立体视觉在提供两个区域之间的相对深度的非常精确的估计方面也是非常有用的。视觉系统如何解决平滑曲面之间的深度估计和检测曲面之间的深度不连续之间的冲突?这一理论的核心假设是,大脑使用物体边界上不匹配的元素来表示边缘的存在,从而定义了不能或不应该被平滑的不连续。
英文摘要
The natural environment contains smooth surfaces defined by edges that define where one object, or surface ends, and the other begins. Many experiments have shown that human visual system is adept interpolating such surfaces using a single cue to depth, stereopsis. However, stereopsis is also extremely useful in providing very precise estimates of relative depth between two regions. How does the visual system resolve the conflict between smoothing depth estimates across surfaces, and detecting the depth discontinuities between them? The hypothesis that is central to this proposal is that the brain uses unmatched elements along an object boundary to signal that an edge is present, and so define a discontinuity that cannot, or should not, be smoothed.
