[Insight-users] create a binary image of a mesh using SpatialObjectToImageFilter

[Luis Ibanez]

Hi Yan,


1) You can simply use an erosion filter with a structuring element
    of radius 1 and then subtract the eroded mask from the
    rasterized mask.


2) Using the TriangleMeshToBinaryImageFilter will also give you a
    rasterized mask with 1s inside and 0s outside. So, there is no
    significant difference with using the SpatialObject.


For details on how to use the Mathematical Morphology filters, please
refer to the ITK Software Guide

   Regards,


     Luis
