[Insight-users] ConnectedThresholdImageFilter, intialize output

[Bryn Lloyd]

Hi,

I am using the ConnectedThresholdImageFilter to segment vessels from MRA 
images (reader -> hessian -> hessian2vesselness -> region growing).
http://www.itk.org/Doxygen/html/classitk_1_1ConnectedThresholdImageFilter.html

Is it possible to setup the filter to use an initial given segmentation.
I guess I could iterate over all pixels and add each object pixel as a 
seed point...

But could I also use the function 
ConnectedThresholdImageFilter::GraftOutput to initialize the filter with 
an intial solution?

Any ideas?


Thanks
Bryn
