Hi again<br>
<br>
As far as I can tell, the segmentation only gives the "closed loops" of the contours in the image. The contours, that are not closed is also of my interest.<br>

Hi Preben,<br>
<br>
You may be interested in the "level set segmentation" methods provided by ITK.<br>
<br>
Please read ITK Software Guide, section 9.3:<br>

Hi<br>
<br>
I'm wondering if it is possible to extract all the contours of the image<br>
automatically.<br>
<br>
I've read in the document Fast Marching Minimal Path Extraction in ITK<br>
(<a href="http://ezctwsgi.maxturnheim.webfactional.com/site_media_ezct/projects/matsur/jell/jell_matsur_aou_12_hea_dr_10_d.pdf" target="_blank">http://ezctwsgi.maxturnheim.webfactional.com/site_media_ezct/projects/matsur/jell/jell_matsur_aou_12_hea_dr_10_d.pdf</a>),<br>
that it is possible to extract a path given an image, a socalled speed<br>
function and a start point and end point. However, I'm interested in all of<br>
the contours of the image - and the start point is not really that<br>
interesting.<br>
<br>
Is this possible?<br>
<br>
<br>
Best regards<br>
Preben<br>
