论文摘要

人类视觉系统的对比敏感性可以从某些低级视力任务(例如视网膜噪声和光学模糊去除)中解释,但不能从其他人(例如变色的适应性或简单瓶颈后的纯重建)中解释。即使在刺激统计数据的实质性变化下,该结论仍然存在,例如考虑类似卡通的图像而不是自然图像(Li等,《视觉杂志》,2022年,预印型ARXIV:2103.00481)。 在本说明中,我们提出了一种生成与(Li等,2022)中使用的统计训练兼容的原始卡通图像。在(Magritte,1929年)中的经典观察之后,提出的方法产生的刺激当然不是它们所代表的:Ceci n'est Pas Une管道。表示形式(提出方法产生的刺激)与现实(实际对象)之间的明确区别避免了最终的问题,用于在学术,非营利性,出版物中使用生成的刺激。

Contrast Sensitivity of the human visual system can be explained from certain low-level vision tasks (like retinal noise and optical blur removal), but not from others (like chromatic adaptation or pure reconstruction after simple bottlenecks). This conclusion still holds even under substantial change in stimulus statistics, as for instance considering cartoon-like images as opposed to natural images (Li et al. Journal of Vision, 2022, Preprint arXiv:2103.00481). In this note we present a method to generate original cartoon-like images compatible with the statistical training used in (Li et al., 2022). Following the classical observation in (Magritte, 1929), the stimuli generated by the proposed method certainly are not what they represent: Ceci n'est pas une pipe. The clear distinction between representation (the stimuli generated by the proposed method) and reality (the actual object) avoids eventual problems for the use of the generated stimuli in academic, non-profit, publications.
