Intensity values, shape index values, and the degree of membership of a GGO juxtavascular pulmonary nodule and its attached vessel. (a) Original CT image; (b) intensity of juxtavascular nodule; (c) shape index values of juxtavascular nodule; (d) the degree of membership of vessel before the fuzzy morphological filtering; (e) the degree of membership of juxtavascular nodule; (f) intensity of vessel; (g) shape index values of vessel; (h) the degree of membership of vessel before the fuzzy morphological filtering; and (i) the degree of membership of vessel after the fuzzy morphological filtering.
