Two different approaches for applying U-net to breast and fibroglandular tissue (FGT) segmentation. The upper figure shows 2C U-nets, where two consecutive U-nets are used. The figure below illustrates the other approach, a single U-net with 3-class outputs. , and denote the probability values of voxels to belong to nonbreast, breast, fat, and FGT, respectively.
