Segmentation of Laser Marks of Diabetic Retinopathy in the Fundus Photographs Using Lightweight U-Net

Figure 5

The ROC curves of the lightweight U-Net, the lightweight U-Net with either postprocessing procedure, and with both postprocessing procedures. The -axis represented the false-positive rate, i.e., 1-specificity, and the -axis represented the true-positive rate, i.e., sensitivity. The area under the curve (AUC) was also calculated, which was presented on the bottom right of the figure. The optimal pair of sensitivity and specificity chosen based on Youden’s index were also marked on the curve, and the precise numeric values were presented on the right side.
