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 … WebFeb 6, 2024 · There are at least seven other indices of lacunarity available in the literature (surveyed in Sect. 2.3 ). While many of these alternative indices are superficially similar to GBL, they do not have a direct relationship to the spatial covariance and therefore do not enjoy the benefits described above. The plan of the paper is as follows.

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.

From lacunarity, we identify … WebThe word "lacunarity" literally refers to a gap or pool as derived from the word for "lake", but in morphological analysis it has been variously defined as gappiness, visual texture, …
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.
WebNov 18, 2016 · The concept of lacunarity is highly scale dependent since heterogeneous textures on small scales can appear quite homogeneous on larger scales. 23 23. R. E. Plotnick, R. H.
