[ITK-users] Ignore background pixels for gaussian filter computations

[Albert Gubern Mérida]

Hi,

I want to compute voxel features using Gaussian filters such as
LaplacianRecursiveGaussianImageFilter in breast x-ray images. However, I
get very strong responses at the skin line due to the large intensity
difference between tissue and backgound. I do have the segmentation of the
background. Is there anyway to exclude/ignore the background voxels from
the computation using a mask or setting a specific intensity value?

Thanks!

Best,

Albert
