The bar graphs describe the percentage of (a) correctly classified oil spill area in the oil spill subset, (b) oil spill misclassified as water in oil spill subset, (c) correctly classified water area in the sea subset, (d) water area misclassified as oil in the sea subset, (e) overall accuracy of oil spill + water, (f) comparison of calculated pixel-based accuracy with the SVM accuracy.
