A Nonparametric Shape Prior Constrained Active Contour Model for Segmentation of Coronaries in CTA Images
Figure 3
Synthetic image shows the intensity distribution along a circular sampled image profile for vascular structure. (a) The synthetic vessel image for straight and Y-shaped segments is depicted. (b) The intensity distribution along the circular sampled profile shown in (a) for straight vessel segment (blue) and vessel bifurcation (red), respectively.
