Any complete theory of human stereopsis must model not only how the correspondences between locations in the two views are determined and the depths are recovered from their disparity, but also how the ambiguity arising from such factors as noise, periodicity, and large regions of constant intensity are resolved and missing data are interpolated. In investigating this process of recovering surface structure from sparse disparity information, using stereo pairs with sparse identifiable features, we made an observation that contradicts all extant models. It suggests the inadequacy of retinotopic representation in modeling surface perception in this stage. We also suggest a possible alternative theory, which is a minimization of the modulus of Gaussian curvature.
如何确定两个视图中位置之间的对应关系以及如何从视差中恢复深度，还必须对如何解决由噪声、周期性和大面积恒定强度等因素引起的模糊性以及如何对缺失数据进行插值进行建模。在使用具有稀疏可识别特征的立体图像对研究从稀疏视差信息中恢复表面结构的过程时，我们进行了一项与所有现有模型相矛盾的观察。这表明在这个阶段，视网膜拓扑表示在建模表面感知方面存在不足。我们还提出了一种可能的替代理论，即高斯曲率模量的最小化。
