[Insight-users] Extract 3D contour from mask image

[Sergio Vera]

Hi Sara

As far as I know, SimpleContourExtractorImageFilter works OK in 3d images.
We have performed some simple test in the past days and it worked. However,
we finally use BinaryContourImageFilter as it seems to be faster:

typedef itk::BinaryContourImageFilter <ITKImgLabelType,
ITKImgLabelType> Contourizer;
Contourizer::Pointer contour = Contourizer::New();
contour->SetInput(img);
contour->SetFullyConnected(false); // true makes thicker contours
contour->SetBackgroundValue(0);
contour->SetForegroundValue(255); // the value of your binary mask
contour->Update()

Regards
