Fig. 7. Examples of the segmentation results for the proposed architecture models again two state-of-the-art methods FrCN²² and CR-UNET³².

Top row shows an example of original mammogram from CBIS-DDSM dataset. Middle row shows an example of original mammogram from INbreast dataset. Bottom row shows an example of original mammogram from the private dataset. Each original mammogram indicates its corresponding ground-truth (binary) image, a segmentation output image of a state-of-the-art model FrCN, a segmentation output image of a state-of-the-art model CR-UNET, vs segmentation output image of the proposed architecture models (Connected-UNets, Connected-AUNets, and Connected-ResUNets).
