A Review on Automatic Mammographic Density and Parenchymal Segmentation

Figure 5

Example mammographic density segmentation. Images (digitised mammograms) from left to right are rated with BI-RADS 1–4, respectively. Fatty, semifatty (e.g., scattered fibroglandular tissue), semidense (e.g., heterogeneous dense tissue), and dense tissue are colour coded as navy, grey, yellow, and red, respectively.
