NEON Tree Genus Classification (ResNet-18)
Classifies tree crowns detected by DeepForest into 60 genera. Trained on RGB imagery from 30 NEON sites across North America.
Trained with NeonTreeClassification.
Usage
from deepforest import main
from deepforest.model import CropModel
detector = main.deepforest()
detector.load_model("weecology/deepforest-tree")
genus_model = CropModel.load_model("weecology/cropmodel-neon-resnet18-genus")
results = detector.predict_tile(path="tile.tif", crop_model=genus_model)
# results has columns: cropmodel_label, cropmodel_score
