[Insight-users] segmented region size..

[Miller, James V (Research)]

You could use the RelabelComponentImageFilter.  Given a segmented image, 
it relabels it such that label 1 is the largest object, label 2 is the next
largest object, etc.  Once the relabeling has been performed, you can query 
the size of a labelled object in terms of number of pixels or volume.

It is a bit of an overkill for the output of the ConnectedThreshold.  We
could add a similar API to the segmentation algorithms. By having the
capability in another filter, we have factored out the capability so it can
used on the output 
of any of the segmentation algorithms.

hi all  .., 
how can i get the region size  (or No. of pixels)
after segmentation ,
the code below give me the whole voulme size 256 x 256
x19  i need only the segmented region .., 
connectedThreshold->Update(); 
ImageType::ConstPointer image  =
connectedThreshold->GetOutput();
ImageType::RegionType   region =
image->GetBufferedRegion();
ImageType::SizeType     size   = region.GetSize();


thanx ,,
