“…Extracting topographic feature lines from point cloud is proposed based on SSV(signed surface variation) and HC-Laplacian smoothing method (Zhou et al, 2016), in which the potential feature points are segmented into different clusters by region growing based on the Euclidean distance and SSV. Some automated algorithms and software of the extraction of ridges or ridge axes from DEMs are still not practical for the applications.…”
