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.
