Fig. 6.

Synthetic lung CT images generated by the proposed method and the other two competitive state-of-the-art image synthesis approaches. The first column shows the segmentation map including the lung (red), ground-glass opacity (blue), and consolidation (green) areas. The second column shows the original CT image. The third, fourth, fifth columns show the synthetic samples which are generated by the proposed method, SEAN [15] and SPADE [14] in order. Each case is presented with zoom in order to show more details, and the yellow arrows point out the special area which is described in the main text.
