[Insight-users] Re: Retaining pixel values in the output of a region growing filter.

[Luis Ibanez]

Hi Roberto,

That's an interesting question.

Unfortunately, the answer is: No, there is no such method.

but

You have an easy option for obtaining the equivalent result:

You can take the output of the itkNeighborhoodConnectedImageFilter
and pass it along with the input image to the MaskImageFilter:
http://www.itk.org/Insight/Doxygen/html/d4/d1b/classitk_1_1MaskImageFilter.html


The output will be such that the pixels of the segmented
region will conserve the original values.

If you want the complementary region you could use the
MaskNegatedImageFilter:

Regards,


     Luis
