Investigation of the performances of advanced image classification-based ground filtering approaches for digital terrain model generation
(John Wiley and Sons Ltd, 2021)
The majority of the ground filtering techniques proposed so far use several user-defined parameter values. Since no standard protocols exist to define these parameters, obtaining the optimum filtering performance is very ...
Automated ground filtering of LiDAR and UAS point clouds with metaheuristics
The ground filtering is essential for the extraction of the topography of the bare Earth surface. Various ground filtering methods have been developed, especially in the last three decades. The main disadvantage of the ...
