I want to isolate parameters such as Tortuosity, Curvature, Torsion, Length, Radius etc. for the centerlines. The current vmtk version groups these centerlines based on Centerline Ids, Group Ids etc.
But it still calculates all the metrics for the centerlines based on CenterlineIds and not based on GroupIds as it should have for parent and daughter branches in the vasculature.
Should I use the Blanking arrays to separate the values along the centerline curves? In that case I would lose out on the centerline metrics for the blanked regions of the arteries.
The other option is to use the Centerline tree which contains the merged network of centerlines near the bifurcations. However this is just an approximation and is not the true representation of the centerlines.
Could you @lassoan suggest a better way to isolate centerline data without using the merged version?
