Figure 6: Multiple lymph nodes and their segmentation result. (a) An original CT image. (b) Edge map given by Canny method; two initial curves for snake deformation are labeled in red and green color; (c) final segmentation result. The initial curves will deform to legitimate nodes even though the initial curve is placed nearing to nearby organs. (d) The nodal area of interested is zoomed in for visual inspection.
