LIDAR DATA FILTERING BASED ON THE IMPROVED WINDOW SIZE OF PROGRESSIVE MATHEMATICAL MORPHOLOGY
Filtering is one of the core post-processing steps of airborne LiDAR point cloud data. It is difficult for traditional mathematical morphology filtering algorithms to preserve sudden terrain features, especially when using larger filtering windows. In this paper, an improved progressive mathematical...
