Tropical tree crown delineation on the raster LiDAR data using watershed segmentation
LiDAR is an active microwave sensor that measures accurate range and position of the observed target. It is useful to estimate the individual tree canopy. Watershed segmentation is one of the methods being used in delineating the tree crown from the Raster LiDAR image. This study assessed the accura...
