Table 2.

Comparison of expert annotations (“E”) versus our method (“M”). For each of the eight BREAST Stamp Project images we analyzed the total acini count and computed the mean, median, and maximum and applied the discretization function D. As this table demonstrates, our method performs comparably with the expert annotations.
