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, … 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.
