Art’s hidden topology: A window into human perception
Fig 19
Analysis of topologically derived features that participants were attracted to.
Each point on the plots is derived from the ECDFs obtained from a single participant viewing a single image. For every image and every participant who viewed the image, a weighted feature map distribution was obtained from: (1) the regions where the participant looked (weighted by gaze duration) and (2) the regions where the participant did not look (uniform weighting). (a) results for persistence feature maps. (b) results for cycle density feature maps. (c) results for cycle perimeter derived maps (exhibitions are indicated in the legends). In each plot in the first two columns, we show MSE on the vertical axis and ME on the horizontal axis, both computed from the difference for each participant, i.e., it compares the ECDF of regions that a participant looked at with the regions that the same participant did not look at. Note that the MSEs between two ECDFs can only lie between 0 and 1, whereas the ME can lie between −1 and 1. The third column shows the distribution of MSEs on which significance tests were conducted. Statistics performed with Mann-Whitney U test, comparing MSE distribution of ECDF between the artistic and pseudo-artistic images, *** p < 0.001.
