Confidence scores reflect the model's certainty, not biological ground truth. The model was trained and evaluated on leaf photos captured under controlled, lab-like conditions, so accuracy on real-world field photos (cluttered backgrounds, variable lighting, multiple or overlapping leaves) may be lower than the reported evaluation metrics.
