Lacunarity indices

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. WebMay 28, 2016 · The lacunarity of a perfectly smooth surface is 1 and this value increases infinitely as the roughness of the surfaces increases. 3.7 3D Moran’s I The Moran’s I index was introduced as a two-dimensional index for spatial autocorrelation in ecological landscapes (Moran 1948; Anselin 1988 ).

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. WebSep 20, 2024 · The lacunarity index (monolacunarity) averages the behavior of variable size structures in a binary image. The generalized lacunarity concept (multilacunarity) on the basis of generalized distribution moments is an appealing model that can account for differences in the mass content at different scales.
