[Insight-users] 3D and 2D image for VED filter

[Wen Shi]

Hi Karthik,
Thanks for your reply.
But I am not familiar with medical image.
So as you said, I need to gather at least four slices images then combine them into one image, then input the
image into the ITK project. Is that what I need to do?

Thanks a lot 

Wen Shi

You need at least 4 slices for the recursive gaussian filter to run. Its used to compute the hessians. Your 3D image is less than 4 slices thick.

Hi Guys, 

When I was using VED filter processing some vessel image, 
I got the error as : 
RecursiveGaussianfilter requires at least 4 pixels along axis 2. 

So I guess the problem is the image I tried to process is a 2D image. 
But to my personal intuition it's a 3D one. 
How to decide the image is 3D or 2D?(maybe this seems pretty stupid and ridiculous but sorry for that). 

Thanks a lot
