Here, cloth simulation filtering (CSF), a verified ground filtering technique used to filter off-ground objects from point cloud in land LiDAR surveys, was adopted and modified. By sequentially filtering the creek points through a hypothetical cloth with an increasingly larger gr...
Inspired by the cloth simulation filter (CSF) proposed by Zhang et al. (2016) for point clouds, we present a novel primitive-oriented cloth simulation algorithm, namely CSF4Geomesh, for the filtering of ground primitives from geomeshes. The main contributions of our method can be exposed as ...
Now we can install CSF from pip as:pip install cloth-simulation-filterHow to use CSF in Matlabsee more details from file demo_mex.m under matlab folder.How to use CSF in RThanks to the nice work of @Jean-Romain, through the collaboration, the CSF has been made as a R package, the...
