Figure 8. ROC curves of the slice-by-slice rejection methods; each curve in the figure was calculated from all the tested datasets combined.

The slice rejection criterion of the gold standard was changed for 1% (a), 1.5% (b), 2.0% (c), and 2.5% (d) of the FOV, and the performances of GMM (red), GMM-cISID (blue), and cISID (black) were evaluated.
