[Insight-users] How to use GeodesicActiveContour with 3D images

[Anders Almås]

Hi!

I am looking at the GeodesicActiveContourImageFilter in the
demo-application. I have seen that it should be able to deal with 3D
images. And my first question is:
Is there any particular 3D images that are intended to use? because I
don't see where they set some parameters about the size and spacing of the
image(for example for *.raw images)
And is there much to change in the 2D version of
GeodesicActiveContourImageFilter? I use that one to a series of 2D images
in png format. My goal is to use those images segmented in 2d as feature
images for 3d segmentation. My segmentation problem is about segmenting
aortic aneurysm..

The final question is about the seed points in the demo application:
The z coordinate, is that just denoting the image slice? or is it a
coordinate as x and y?
