Lacunarity indices

WebLacunarity is a counterpart to the fractal dimension that describes the texture of a fractal. It has to do with the size distribution of the holes. Roughly speaking, if a fractal has large gaps or holes, it has high lacunarity; on the other hand, if a fractal is almost translationally invariant, it has low lacunarity. WebOct 15, 2009 · Lacunarity features are used to assess the largeness of gaps or holes of complex signals and images. As it stands, the lacunarity analysis used is an index averaging the behavior of small- and large-size structures in a given set. The aim of this work is to propose a generalized lacunarity concept on the basis of generalized moments.

WebThe so-called “gliding box method” of lacunarity analysis has been investigated for implementing multifractal modeling in comparison with the ordinary box-counting method. Newly derived results show that the lacunarity index is associated with the dimension (codimension) of fractal, multifractal and some types of nonfractals in power-law … WebLacunarity is a counterpart to the fractal dimension that describes the texture of a fractal.

A Lacunarity-Based Index for Spatial Heterogeneity

WebJul 19, 2024 · Lacunarity analysis is a popular occupancy-based method for identifying relevant length scales in spatially heterogeneous systems. From lacunarity, we identify the existence of a point which encapsulates the spatial heterogeneity of a given system. WebJun 24, 2024 · The lacunarity analysis can be applied to data of any dimension and to binary or quantitative data, and both fractal and nonfractal patterns can be analyzed. Therefore, the lacunarity can be considered as a scale-dependent measure of heterogeneity or texture of an object, whether or not it is fractal (Dong 2009 ).
