Influence of the breast density on the proposed detection algorithm.

MIAS
Density	F	G	D	—	All
Proportion	44%	36%	20%	—	100%
Sens	90.9%	94.44%	90%	—	92%
FPI	1.77	2.05	2.1	—	1.94
DDSM
Density	1	2	3	4	All
Proportion	7.69%	23.84%	36.92%	31.53%	100%
Sens	90%	96.77%	93.75%	92.68%	93.84%
FPI	1.2	2.0	2.08	2.75	2.21

The first row shows the quantity proportion of each subset with different densities on both MIAS and DDSM data sets. The metrics are Sens and FPI.
