It has often been conjectured that the effectiveness of line drawings can be explained by the similarity of edge images to line drawings. This paper presents several problems with explaining line drawing perception in terms of edges, and how the recently-proposed Realism Hypothesis of Hertzmann (2020) resolves these problems. There is nonetheless existing evidence that edges are often the best features for predicting where people draw lines; this paper describes how the Realism Hypothesis can explain this evidence.

边在画线感知中的作用

人们经常猜想，线条图的有效性可以通过边缘图像与线条图的相似性来解释。本文提出了一些问题，这些问题用边缘来解释线图感知，以及最近提出的赫兹曼（Hertzmann）的现实主义假说（2020）如何解决这些问题。但是，现有证据表明，边缘通常是预测人们在哪里画线的最佳功能。本文描述了现实主义假说如何解释这一证据。
