“…The features are usually computed from points and neighbours that represent the local object structures. For determining the spatial structure for each point under consideration, various neighbourhood types, such as spherical (Brodu and Lague, 2012), cylindrical (Filin and Pfeifer, 2005), and k-nearest neighbourhoods (kNN) (Weinmann et al, 2015;Seyfeli and Ok, 2022), are favoured. In this context, establishing a neighbourhood relationship with kNN is one of the main issues.…”

“…The height difference between the lowest and highest points (ΔH = hmax -hmin) and the standard deviation of the height (σH) of all points in the local relations are additional features obtained from height. Verticality (V) is the final geometric property (Seyfeli and Ok, 2022). Moreover, the eigenvalues λ1,2,3 have great potential to calculate local shape properties, including dimensionality (linearity, planarity, and sphericity) in the local neighbourhood (Demantké et al, 2012), and other measures such as omnivariance, anisotropy, eigenentropy, sum of eigenvalues, and change of curvature.…”
