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.<br><br><div class="gmail_quote">On Fri, Mar 13, 2009 at 6:56 PM, Wen Shi <span dir="ltr"><<a href="mailto:wsa18@sfu.ca">wsa18@sfu.ca</a>></span> wrote:<br>

<br>
When I was using VED filter processing some vessel image,<br>
I got the error as :<br>
RecursiveGaussianfilter requires at least 4 pixels along axis 2.<br>
<br>
So I guess the problem is the image I tried to process is a 2D image.<br>
But to my personal intuition it's a 3D one.<br>
How to decide the image is 3D or 2D?(maybe this seems pretty stupid and ridiculous but sorry for that).<br>
<br>
Thanks a lot<br>
<br>
Wen SHi<br>
