Anisotropic tubular minimal path model with fast marching front freezing scheme
作者:
Highlights:
• We establish a new anisotropic geodesic metric in a radius-lifted space in order to avoid the short branches combination problem.
• We extend the front frozen scheme from the isotropic metric to a radius-lifted space through an anisotropic Riemannian metric by using the non-local path feature.
• We make use of a crossing-adaptive tensor field established in the radius-lifted space, the anisotropy of which is kept in non-crossing vessel region and removed in crossing points.
• We consider three different types of scale function in the tensor field to reduce the influence from the regions outside the vessel structures including vesselness map, a binary-valued function and the skeleton map.
