Art’s hidden topology: A window into human perception

Average group persistence landscapes for BW filtration.
The average persistence landscape was computed for each group: art (a,c) and pseudo-art images (b,d), with results for dimensions 0 shown in the top row and dimension 1 in the bottom row. Every individual landscape was constructed from cycles of persistence greater than 5 pixel intensity values [54]. The average landscapes for artistic and pseudo-artistic images were significantly different for each dimension under the non-parametric Wilcoxon test with permutation, both p < 0.001. A marked difference in structural richness between the two groups of images is again evident, as persistence landscapes in both dimensions contain significantly more layers for artistic images.
