Notes. Segmentation scores evaluated on the Galactic plane segmented by the models reported in Figure 14. Precision, recall, dice index, and MS rate are evaluated at classification threshold values of 0.8, 0.5, 0.2, and the optimal threshold. The latter refers to the threshold value optimizing the dice index and estimated using P-R curves (see Figure 15c). Blue (red) refers to the best (least performing) scheme in each row. The bold scores correspond to the absolute best (if in blue) or lowest (if in red) performance per score. Overall, the segmentation scores obtained on the fully segmented Galactic plane consolidate the results obtained with the zone of 350.3–353.5° in Table 4
