根据人类视觉运动中小孔问题(Aperture Problem)的观点,如果通过小孔观察一个运动的光栅,那么人类视觉系统能够检测的唯一运动只有光栅的法向运动分量。本文设计了一系列不同形状的窗口,研究窗口内视觉系统的局域运动知觉。研究结果表明,窗口内视觉系统的局域运动知觉,包括主观运动方向和速度大小,取决于窗口的形状及光栅的朝向。传统的小孔问题的观点显然是片面的。 According to the Aperture Problem in Human Visual Motion, if a moving grating is viewed through a pinhole, the only motion the human visual system can detect is the normal motion component of the grating. In this paper, a series of windows with different shapes are designed to study the local motion perception of the visual system in the window. The results show that the perception of local motion in the intra-window vision system, including subjective motion direction and velocity, depends on the shape of the window and the orientation of the grating. The traditional point of view of the hole is obviously one-sided.
