Automating Tree Crown Delineation in UAV Orthomosaics Without Annotation: An Annotation-Free Framework Coupling DeepForest, Segment Anything, and Unsupervised Clustering

Individual-tree-level information on crown distribution and morphology underpins forest inventory, biomass estimation, and carbon accounting. High-resolution Unmanned Aerial Vehicle (UAV) imagery resolves single-tree detail, but automated crown extraction remains difficult: fully supervised segmentation depends on cost...
