Automatic Histogram Specification for Glioma Grading Using Multicenter Data

Table 3

Results of the first three glioma grading experiments.

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