The receiver operating curves (ROCs) for the predictive models were generated to discriminate RE and IRE zones by developing region-based and pixelwise classification models with random forest technique. (A) represents ROCs for the training of the region-based classifier while (B-D) represents ROCs for training, validation, and test sets for the pixelwise classification model.
