Art’s hidden topology: A window into human perception
Fig 14
Average Betti curves with 1 standard deviation above and below shaded, together with individual Betti curves for each image for the BW filtration.
The average Betti curve was computed for each group: artistic and pseudo-artistic images, with results for dimension 0 (a) and dimension 1 (b). S8 Fig shows Betti curves for the WB filtration. The numbers of holes and cycles reflected here by the Betti curves is significantly different for artistic and pseudo-artistic images.
