[Insight-users] SimpleITK FastMarching

[Reuben Middendorf]

Hi Brad,

seed.push_back([128,128]); seems to give the same error

I modified the code to:

.....
        org.itk.simple.VectorUIntList seed = new
org.itk.simple.VectorUIntList();
        org.itk.simple.VectorUInt32 pts;
        pts = new org.itk.simple.VectorUInt32(2);
        pts.push_back(128);
        pts.push_back(128);
        seed.push_back(pts);
        org.itk.simple.FastMarchingImageFilter waveProp = new
org.itk.simple.FastMarchingImageFilter();
        waveProp.setTrialPoints(seed);
.....

This compiles, but I'm unsure whether this is doing what I'm expecting.
I'll find out when my full code runs, I guess, but if you can tell offhand
if this is doing something bizzare, please let me know.

Regards,

Reuben
