Perhaps your mask and input images have different locations in physical space.

Oddly the contour is at the correct iso-curve on the original image (in vtkImageViewer2).<br>
<br>
Eg. If I set<br>
myVtkImageViewer2->SetInput( orig );<br>
<br>
contourer->SetInput( mask )<br>
contourer->SetValue(0, 2);<br>
<br>
The iso-contour shows up corresponding to intensity=2 on the image=orig. Though, the contourer should generate the same for image=mask !<br>
<br>
Thanks !<br>

<br>
could you elaborate on the problem - is the contour showing up, but in the wrong place? or is it just not showing up at all?<br>
