Fig. 8.

Radar plots of the quantitative metrics. Results are shown for three metrics, five DIRNet models, and three organs averaged over 15 patients. The colored polygon represents the organs (blue: cervix, red: bladder, and green: rectum). Each corner corresponds to a variant of DIRNet models. Each model has three scores (at the corners) for three organs. For the Dice measure (left plot), the DIRNet 4 has a greater dice score relative to all other DIRNet variants, except for the DIRNet 3 in the bladder. Similarly, for the Jaccard coefficient (middle plot), the DIRNet 4 has a greater score for all organs, in comparison with all other DIRNet variants. Regarding the average symmetric surface distance (ASSD) (right plot), the DIRNet 4 also has a lower score (best match) for all organs, and the DIRNet 3 has a similar ASSD score as the DIRNet 4 for the cervix
