Table 3.
Evaluation results on clinical noncontrast CT cases. F1 scores are reported (leave-one-out and three-fold CV leaving one subject out) for the three evaluation stages: random forest (RF), graph-cuts (GC) and final refined graph-cuts (Ref. GC). The last two rows show the mean and standard deviation values.
