Hi Sebastien,<br><br><br>1) Yes, you could simply use the <br> <br> itkBinaryThresholdImageFilter<br><br> and set the threshold values to match <br> the label that you want to extract.<br><br><br>2) Once you extract that label,<br>
you could generate a surface by<br> converting the image to vtkImageData<br> and using the vtkContourFilter.<br><br>See examples in<br> <br>InsightApplications/Auxiliary/vtk/<br> ExtractIsoSurface.cxx<br>

<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div>Hi!</div>
<div> </div>
<div>I would like to extract a specific region from the ouput of a watershed segmentation. The output of the segmentation filter is a labeled image where each pixel is assigned an unsigned long integer label that groups it within a connected region.</div>
<div> </div>
<div>1) Is it possible to get the label corresponding to a specific region (for example, by specifiying a pixel belonging to the region of interest) ?</div>
<div> </div>
<div>2) Is it possible to extract the surface corresponding to a specific region (for example, by specifying the region's label) ?</div>
<div> </div>
<div>Thanks for your help</div>
