[Insight-users] Using the Fast Marching filter from python

[Patrick]

Hi all,

I am completely new to ITK but rather impressed by the breadth of 
algorithms it contains. In my particular application I would like to 
apply a Fast Marching filter to calculate the arrival time of a wave at 
voxels in a 3d image starting from a user specified seed point. The 
ItkSoftwareGuide contains an excellent example of how to do this in C++, 
however, in Python I am not sure how to pass the seedpoints to the 
algorithm. In C++ the "NodeContainer" type of the FastMarchingFilter is 
used.
My question is, how do I pass a numpy-array into this data structure 
from Python?

Thanks!

Regards,

Patrick
