1/f-noise structures in Pollocks's drip paintings

The fractality and scaling properties of luminance patterns in Pollock's drip paintings, are studied in this paper. The painting is represented as a matrix array where each entry represents the luminance at the corresponding canva position. Detrended fluctuation analysis (DFA) is used to characterize fractality, and the results show that the whole luminance pattern is indeed fractal. Interestingly, the fractality is associated to 1/f-noise structures, which can be inducing the aesthetic properties of the artistic object. In fact, for spatial scales below 30cm, Pollock's drip painting are organized as 1/f-noise structures, which presumably are attuned for pleasant (i.e., aesthetic) perception.
