Art’s hidden topology: A window into human perception
Fig 17
Cycle density comparison for all images (a) and the two closest cross-group samples of cycles visualisation (b,c).
Every curve in (a) represents the ECDF of the cycle density distribution for images for both exhibitions; the density used for ECDF is the sum of densities from BW and WB filtrations; artistic (green) and pseudo-artistic (orange). The vertical axis is the proportion of all windows from a grid mesh. All curves were statistically different under the Kolmogorov-Smirnov test. Images for which cycles were visualised are those marked with ‘*’ in the figure with ECDF plots. The cycle density reflects the texture of an image, i.e., the spatial distribution of changes in contrast.
