Coronary Artery Center-Line Extraction Using Second Order Local Features
Figure 15
The average performance results calculated by applying the proposed tracing algorithm on the vessel segments with equal curvature values, varying arc-length, constant taper value, and no stenosis in image group 3. (a) No adaptation schema is used for the step size. (b) The step size is adapted based on angular difference between the current and previous estimates of the vessel direction.
