An Improved Fuzzy Connectedness Method for Automatic Three-Dimensional Liver Vessel Segmentation in CT Images

Figure 9

Comparison of the improved fuzzy connectedness (FC) method with traditional segmentation algorithms. Each column corresponds to one case. The original CT images of each case are shown in Figures 7(j)–7(r). (a)–(c) The gold standard of liver vessel. (d)–(f) The vessel segmented by using the improved FC. (g)–(i) The vessel segmented by using traditional FC with multiple potential seeds indicated by the blue points in Figure 2(b). (j)–(l) The vessel segmented by using traditional FC with one single seed indicated by the red point in Figure 2(b). (m)–(o) The vessel segmented by using region growing with multiple potential seeds. (p)–(r) The vessel segmented by using threshold level set with multiple potential seeds.
