“…A multifractal object is described by multiple characteristic fractal dimensions (Stach and Cybo, 2003). The obtained trend of the multifractal behaviour was derived from the amount of q-values for the generalised fractal dimensions presented in Table 2 (D 0 , D 1 , D 2 , D 3 ) which were required to describe the self-similitude spectra (Mendoza et al, 2010).…”
