I would smooth the binary field with GaussianFilter and compute the
gradient, this will give you an approximated normal direction.<br><br><div class="gmail_quote">On Sat, Feb 27, 2010 at 3:06 PM, J. Pura <span dir="ltr"><<a href="mailto:puraj@mail.nih.gov">puraj@mail.nih.gov</a>></span> wrote:<br>

Hello,<br>
<br>
I would like to know if there is a convenient way in itk to extract the<br>
surface normal of a 3D binary object at a specific point, or even for a<br>
small neighborhood of points.<br>
<br>
Thank you,<br>
<br>
John<br>
