Table 3.
The Az values for LDADI and BNNDI classifiers designed using features extracted from the segmented masses on US images for the two cycles of cross validation. The mass centers identified by R1 and R2 were used for initialization of segmentation by active contour model.

|---|---|---|---|---|
| Test P1 (train P2), centroid by R1 | 0.91±0.02 | 0.91±0.02 | 0.91±0.02 | 0.91±0.02 |
| Test P2 (train P1), centroid by R1 | 0.91±0.02 | 0.88±0.02 | 0.91±0.02 | 0.88±0.02 |
| Test P1 (train P2), centroid by R2 | 0.91±0.02 | 0.86±0.02 | 0.91±0.02 | 0.86±0.02 |
