Examples of segmentation at axial slices (In each sub-figure, there are three columns: the left the left column shows the results of manual segmentation of lung field including both lung parenchyma and lesions; the middle column presents the results of segmentation of lung parenchyma by our proposed method; the right column shows the results after a “hole-filling” operation from those by our method.). a Three example slices (three rows) for subjects with COPD. b Three example slices for subjects with lung cancer (CT scanner)
