Mendeley supplemental figure 1

Few examples of images from the man vs. machine comparison which were either misdiagnosed by humans or network. Images are grouped in true diagnosis ulcus cruris (UC) and pyoderma gangrenosum (PG). Guided Grad-CAM and Grad-CAM highlight the structures and areas that would lead the network towards a PG diagnosis. For the wrong UC interpretation (two leftmost columns) the CNN is misled by only small parts of the wounds, whereas for the correct PG diagnoses (two rightmost columns) the CNN accounts for the reddish area surrounding the lesion and the irregular wound border in the left bottom wound area.
