Previous studies have demonstrated that the onset of temporal aliasing artifacts occurs when the spatial displacement between samples reaches a critical distance, and that subsequently a linear relationship exists between stimulus speed and critical sampling rates. In this paper, we carry out further experimentation using a novel experimental setup, in which a strobe light is used to emulate impulsive temporal sampling, in order to investigate the spatiotemporal envelope of the human visual system and the effect of a stimulus. For non-periodic stimuli, experimental results show that critical sampling rates increase with motion speed and decrease with stimulus width. These interactions can be described using simple log-linear models, and characterized using the temporal aliasing visibility function, where maximum critical frame rates up to 1500 Hz are predicted. For periodic stimuli, we demonstrate that both perceptible temporal aliasing artifacts and stimulus aliasing can cause stroboscopic effects.

通过时间混叠伪影的可见性来表征人类视觉系统的时空包络。

先前的研究表明，当样本之间的空间位移达到临界距离时，会出现时间混叠伪影的发生，并且随后在刺激速度和临界采样率之间存在线性关系。在本文中，我们将使用新颖的实验装置进行进一步的实验，其中使用频闪灯来模拟脉冲时间采样，以研究人类视觉系统的时空包络和刺激的效果。对于非周期性刺激，实验结果表明，临界采样率随运动速度而增加，而随刺激宽度而减少。可以使用简单的对数线性模型来描述这些相互作用，并使用时间混叠可见性函数来表征这些相互作用，预测最大关键帧速率可达1500 Hz。对于周期性刺激，我们证明可感知的时间混叠伪影和刺激混叠均会引起频闪效应。
