[Insight-users] Re: Need a Help in ITK : How to find bounding box of an image region.

[Luis Ibanez]

Hi Ihab,

You can use the following code for finding the bounding box of the
non-zero content of your image:

   typedef itk::ImageMaskSpatialObject< 3 > ImageMaskSpatialObjectType;

   ImageMaskSpatialObjectType::Pointer
      imageMaskSpatialObject  = ImageMaskSpatialObjectType::New();

   imageMaskSpatialObject->SetImage ( inputImage );

   MaskFloatImageType::RegionType boundingBoxRegion =
     imageMaskSpatialObject->GetAxisAlignedBoundingBoxRegion();


If your image doesn't have full zeros outside of the brain, then you
should threshold it first, before passing it to the ImageMaskSpatial
Object.


    Regards,


       Luis
