Table 7 Image classification accuracy by group in two classes where A + B + C = alive trees, D = dead trees, PA = producer’s accuracy, UA = user’s accuracy, value shown in bold = overall accuracy

From: Assessing a novel modelling approach with high resolution UAV imagery for monitoring health status in priority riparian forests

		Predicted
