[Insight-users] [ITK Community] Fwd: Problem with .Tiff and surgace extraction in ITK

[Matt McCormick]

Hi Jaume,

This example that uses the BinaryMask3DMeshSource [1] may help.

A binary input can be smoothed before surface extraction as shown here [2].

A mesh can be written to a file as shown here [3].

To transfer the image in memory to VTK, use the ImageToVTKImageFilter from
VtkGlue module [4].

Hope this helps,
Matt
