[Insight-users] question on fast marching

[qxue at jouy.inra.fr]

Hello, ITK users:

    I am using FastMarchingImageFilter to do segmentation.
    If I use it directly after reading the file, everything is fine. However,
when  I add LaplacianRecursiveGaussianImageFilter into the pipeline
(ReadFileFilter->LaplacianGaussianFilter->FastMarchingFilter->WriterFileFilter),
there will be result, that is, the whole image is black.
    Thanks in advance.
