Málaga Database

The performance of our approach has also been evaluated using a set of $35$ cases containing masses from the Málaga mammographic database (see Appendix  for more information). Since each case has both CC and MLO views of the breast, we can study the performance of our method using mammograms of each view.

One of the main features of this database is that the ground-truth of the masses is provided by six experts. In the evaluation of our results only the pixels where all radiologists agree are considered as mass, while the rest of pixels are considered normal tissue (we will see in next section that the results are not highly dependent on this parameter). As all the database cases contain masses, we only evaluated our approach using ROC analysis.
