- Method / resource At 60 m, YOLOv8 crown delineation had the highest accuracy, F1 about 0.88.
- Method / resource YOLOv8 had the highest precision under optimal flight conditions but greater variability with flight geometry changes.
- Method / resource YOLOv11 had stable performance across acquisition conditions with generalization gaps below 0.02.
- Association Vertical position and crown morphology influenced species-level detection accuracy.
- Observation Cedrelinga cateniformis had dominant asymmetric crowns.
- Observation Calycophyllum spruceanum had narrow co-dominant crowns.
- Observation Virola pavonis had symmetrical intermediate crowns.
