Percent density (PD) and generalized energy distance (GED) for CM-YNet (mask).

Dataset	#Images	R1 vs. R2	PD-R1	PD-R2	%(R1 > R2)	GED
GVA(train)	2496	0.76 ± 0.17	0.19 ± 0.13 *	0.16 ± 0.12	73.31	3.13 ± 0.44
GVA(test)	844	0.77 ± 0.15	0.19 ± 0.14 *	0.16 ± 0.13	68.36	3.16 ± 0.40
IMIM	381	0.72 ± 0.20	0.17 ± 0.15	0.14 ± 0.11	62.2	2.80 ± 0.56

The DICE score between R1 and R2, and the percent density (PD) for each annotator are shown as mean ± standard deviation. The percentage of samples in which PD-R1 was larger than PD-R2 is shown in the column %(R1 > R2). The last column shows the generalized energy distance (GED) between the annotator’s labels and the estimated segmentation for each annotator. * The difference between the percent density (PD) obtained by R1 and R2 was statistically significant (p < 0.00001)
