几何学与视觉感知密切相关；然而，除了早期的视网膜组织外，人们对视觉加工的几何学知之甚少。我们提出了各种知觉现象，表明视网膜再现既不足以支持形式知觉，也不必要。我们讨论了流行的“对象文件”概念作为非视网膜主题表示的候选概念，并根据其不足之处，提出了使用局部流形表示的未来研究方向。我们认为这些流形是由运动分割产生的动态参照系的出现而产生的。我们还认为这些流形的度量是基于相对运动矢量的。
Geometry is closely linked to visual perception; yet, very little is known about the geometry of visual processing beyond early retinotopic organization. We present a variety of perceptual phenomena showing that a retinotopic representation is neither sufficient nor necessary to support form perception. We discuss the popular “object files” concept as a candidate for non-retinotopic representations and, based on its shortcomings, suggest future directions for research using local manifold representations. We suggest that these manifolds are created by the emergence of dynamic reference-frames that result from motion segmentation. We also suggest that the metric of these manifolds is based on relative motion vectors.
