Motion is easy to see

In this image I am visualizing where the perfect centerline is unclear by motion. I generated several centerlines for the same arteries from multiple starting points. The places you see moving are where the centerline algorithm was unsure where to put the centerline and drew different centerlines based on the starting point. The motion in the image makes it clear to the eye where the centerline is ambiguous. Making your data move is a great way to see what's going on.
Centers of the same arteries, moving centerlines are where the algorithm is less sure
