Tree Segmentation

Traditional methods for segmenting trees attempt to isolate prominent tree crowns from a lidar-derived canopy height model. This group of researchers have introduced a novel segmentation method, “layer stacking,” which slices the entire forest point cloud at 1-m height intervals … Continue reading
