%description
Methods for the computation of surface/image texture indices using a
geostatistical based approach (Trevisani et al. (2023)
<doi:10.1016/j.geomorph.2023.108838>). It provides various functions for
the computation of surface texture indices (e.g., omnidirectional
roughness and roughness anisotropy), including the ones based on the
robust MAD estimator. The kernels included in the software permit also to
calculate the surface/image texture indices directly from the input
surface (i.e., without de-trending) using increments of order 2. It also
provides the new radial roughness index (RRI), representing the
improvement of the popular topographic roughness index (TRI). The
framework can be easily extended with ad-hoc surface/image texture
indices.
