Abstract

Whether apparent motion occurs only between targets of similar spatial frequency was examined. A "crossed phi" method was used, in which two potentially different targets exchange position. If the targets differ in a feature that controls apparent motion then they will appear to move so as to exchange positions; if they differ in an irrelevant feature, no apparent exchange will occur. It was found that apparent motion occurs only between similar spatial frequencies. This result is interpreted in the light of recent models of human visual motion sensing, in which motion estimates are computed separately within a number of spatial frequency bands.

摘要

研究了明显运动是否仅发生在具有相似空间频率的目标之间。采用了一种“交叉φ”方法，即两个可能不同的目标交换位置。如果目标在控制明显运动的特征上有所不同，那么它们将看起来移动以交换位置；如果它们在无关特征上有所不同，则不会发生明显的交换。结果发现，明显运动仅发生在相似的空间频率之间。根据人类视觉运动感知的最新模型对这一结果进行了解释，在这些模型中，运动估计是在多个空间频率带内分别计算的。
