Table 4:

Localization performance of GMIC on malignant (M) and benign (B) lesions. We adopt Dice similairty score (DSC) and pixel average precision (PxAP) as evaluation metrics. We compared GMIC with U-Net and a random baseline whose pixel-level predictions are randomly drawn from the standard uniform distribution.

Model	DSC(M)	DSC(B)	PxAP(M)	PxAP(B)
GMIC	0.325 ± 0.231	0.240 ± 0.175	0.396 ± 0.275	0.283 ± 0.244
U-Net	0.504 ± 0.283	0.412 ± 0.316	0.589 ± 0.329	0.498 ± 0.357
random	0.039 ± 0.044	0.021 ± 0.030	0.012 ± 0.015	0.006 ± 0.010
