[vtkusers] Generate contours around the segmented regions

[Xiaopeng Yang]

Hello VTK users,

 

After segmentation, I would like to generate contours around the segmented
regions. And then visualize the contours over the original images. However,
The generated "contours" look like 3D surface, not 2D contours (see the
following image). Do you guys know what's going on?

 

The code for generating contours:

 

vtkContourFilter * contour = vtkContourFilter::New();

contour->SetInput( vtkImporter2->GetOutput() );

contour->SetValue(0, 128); // edges of a binary image with values 0,255

 



 

Thanks a lot,

Yang
