Lakunarität
WebLacunarity analysis was also employed in discriminating between multifractal grayscale patterns with the same D2 values, but different degrees of scale-dependent clustering. For this purpose, a new lacunarity parame-ter, L, was formulated based on the weighted mean of the log-transformed lacunarity values at different scales.

Since the default is 2.0 the passes are called 'octaves'. Changing this affects the visual feel, though I've not seen a good reference to describe it either. Higher values tend to get small features sticking out of the smooth general pattern, like Martian boulders, while ...
The data gathered for each ε {\displaystyle \varepsilon } are manipulated to calculate lacunarity. One measure, denoted here as λ ε {\displaystyle \lambda _{\varepsilon }} , is found from the coefficient of variation (C V {\displaystyle {\mathit {CV}}} ), calculated as the standard deviation (σ {\displaystyle \sigma } ) … See more Lacunarity based on λ ε , g {\displaystyle \lambda _{\varepsilon ,g}} has been assessed in several ways including by using the variation in or the average value of λ ε , g {\displaystyle \lambda _{\varepsilon ,g}} for … See more Other methods of assessing lacunarity from box counting data use the relationship between values of lacunarity (e.g., λ ε , g {\displaystyle \lambda _{\varepsilon ,g}} ) … See more Another proposed way of assessing lacunarity using box counting, the Prefactor method, is based on the value obtained from box counting for the fractal dimension (D B … See more http://paulbourke.net/fractals/fracdim/

This property can be qualitatively seen to encode a lacunarity of the fractal structure [1]. 2Here, we implicitely assume that a change of scale leads to a change of control parameter as in the renormalization group formalism. More directly, x can itself be a scale. 3This is only true for a function of a single parameter. Homogeneous ...
