Art’s hidden topology: A window into human perception
Fig 18
Comparison of how topological features were explored in both exhibitions.
MSE between image features distribution ECDF and the features weighted by each participant’s gaze duration data. MSEs between two ECDFs can only lie between 0 and 1. Results for: (a) Persistence; (b) Cycle density; (c) Cycle perimeter. (Exhibitions are indicated on the axis; only laboratory data was used for this comparison). The line-up of plots within each subfigure is as in Fig 11. The Mann-Whitney U test, comparing MSE distribution for the artistic images to MSE distribution for the pseudo-artistic images, yielded significance for a) and c), *** p < 0.001.
