Table 1.
Cross-validation performance of the automatic segmentation. Manual Vol is the mean volume of the manual segmentation in mm3; Auto Vol is the mean volume of the automatic segmentation in mm3. CC is the Pearson correlation coefficient between Manual Vol and Auto Vol; TPR: mean true positive rate; FDR: mean false discovery rate. Numbers in parentheses indicate standard deviations. NA: nucleus accumbens, BF: basal forebrain, SepN: septal nuclei, HTh: hypothalamus without mammillary bodies, MB: mammillary bodies, Fx: fornix, L: left, R: right. The table reflects only data from the 18 independent test subjects.
