[Insight-users] BilateralFilter parameters questions

[siqi chen]

1. Radius is just the truncated domain kernel that you wanna constrain the
computation. So it is related to the Domain sigma.  Typically, it is set to
be 2.5*DomainSigma if you turn the AutomaticKernelSize On and set m_DomanMu
to 2.5


2. AutomaticKernelSizeOn only control domain kernel (Radius).  Range kernel
is automatically set as m_RangeMu*m_RangeSigma
