Hi Taru,<br><br>You may want to do the following:<br><br><ul><li>Use the itkConnectedComponentImageFilter <br>on the resulting segmentation</li><li>Then use the itkBinaryMask3DMeshSource<br>to extract an itkMesh for each one of the labels<br>
in the connected components image</li><li>Finally use the itkVTKPolyDataWriter to write<br>the itkMeshes in to .vtk legacy files.</li></ul><br>Then to display the sufaces, yes, you need to create<br>a vtkActor for each one.<br>
<br>See for example:<br><br>InsightApplications/Auxiliary/vtk/<br> itkReadITKImage3DSegmentShowVTK.cxx<br> itkReadITKImageSegmentShowVTK.cxx<br><br><br><br>Regards,<br><br><br> Luis<br><br><br>-----------------------------<br>

Hello,<br> <br>I am new to VTK. I have segmented a 3D MR volume using ITK-SNAP and now need to process each of these segmented structures using VTK.<br> <br>ITK-Snap allows me to save either the entire 3D segmentation or the individual mesh structures. <br>
<br>Could you please guide me regarding the best way to extract the individual segmented structures from the full 3D segmented image (single image with all the segmented str not the individual meshes) so that I can process them individually(vtk filters - decimation etc) and create polygonal mesh models for each and finally a 3D volumetric model using all these meshes. <br>
<br> <br>Also, as per my understanding, I will need to create one vtkActor for each of the segmented structures. Please advise if this is the right way to do it ?<br> <br>I will really appreciate your help.<br clear="all">
