<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px 'Times New Roman'">I managed to start run the GeodesicActiveContoursFilter. I forgot to the lin<span style="font: 16.0px Arial">e</span></p>

<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px 'Times New Roman'">I wanted to use the SignedDanielssonDistanceMapFilter, but i get the same problem as before putting the line above as a result.</p>
<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px 'Times New Roman'">Is there something similar for the SignedDanielssonDistanceMapFilter to set?</p>

<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px 'Times New Roman'">My second question is regarding the time used for the segmentation</p>
<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px 'Times New Roman'">I tried to use it on a MRI t2_3D, 256 slices 40 Iteration steps, but it took me more then 4 minutes. Is this a normal behaviour that i should expect on Leopard 10.6 16 GB RAM?</p>

<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px 'Times New Roman'">I still think i am missing something because i don't see a connection between the image and the segmented region. (Which leads me to my third question, what does the DistanceValue in the fastMarching means- it just doesn't make sense to me when starting with a seed point only and not with some initial contour).</p>
<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px 'Times New Roman'">I send some images maybe this will help to help me:P</p>
<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px 'Times New Roman'">i didn't put all of them, but Test4 is the one where i put my seed point.</p><p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 16.0px 'Times New Roman'">https://picasaweb.google.com/ellaMkadas/TestLevelSet?authkey=Gv1sRgCMrzgp3nsPfWeg#</p>
