Hi, Yongqiang,
Those parameters should be estimated from training sample regions which =
usually be specified by a GUI system. You can also take the neighborhood =
regions of seed points to estimate those parameters. That paper you =
mentioned has been published on Graphical Models 64 (2003) 259-281.

Subject: [Insight-users] How to compute the parameters of =
VectorFuzzyConnectednessImageFilter?
Hi all,
I want to use fuzzy connectedness method to segment MRA images, =
but after I read the description of this filter and the test file =
"itkVectorFuzzyConnectednessImageFilterTest.cxx", I really don't know =
how to get some parameters that filter needs.=20
In test file, the parameters including ObjectMean and ObjectMatrix are =
set by hand, I think this method is not feasible. In another point, I =
can not find the paper "Fuzzy-connected 3D image segmentation at =
interactive speeds", so it is hard to read the source code.
Can someone tell me how to compute these parameters?
Thanks!!
