[Insight-developers] Not work when using BilateralImageFilter

[Xiaoxiao Liu]

Hi XiongXiang,

Did you set the sigmas ?:

  bilateralFilter->SetDomainSigma(domainSigma);
  bilateralFilter->SetRangeSigma(rangeSigma);


Here is an example of using BilateralImageFilter:

It's better to post your full section of code and the corresponding testing
image for others to give a full diagnosis.
