Results of the contrast experiment.

Training	Testing	Method	AUC	ACC (%)	SEN (%)	SPE (%)
(80%) (GH + BT) + (20%)	(GH + BT)	HE	0.9176	86.19	90.44	76.05
(80%) (GH + BT) + (20%)	(GH + BT)	Handpicked	0.9447	89.90	90.35	88.88
(80%) (GH + BT) + (20%)	(GH + BT)	Our method	0.9786	94.13	94.64	93.00

Note: GH is for GliomaHPPH2018, and BT is for BraTS2017. GH + BT represents 80% of the data as training and 20% as testing.
