[Insight-developers] fast marching and paths

[Richard Beare]

Hi everyone,

One of the widely reported applications of fast marching is in various
forms of path extraction. I believe this is done by computing the
arrival times at every point using fast marching and then backtracking
to the source point using gradient information. I haven't been able to
find any support for this in the ITK fast marching filters - can
anyone suggest where it might be hidden away?

Thanks
