[Insight-users] Re: Is there any filter which can give out the center of labels on the labeled image

[Alireza Salamy]

Hi Bill,
  I  simply add 
  const unsigned long index1= region.GetIndex(labelValue );
  to the code itkLabelStatisticsImageFilter.cxx but it returns index1=0 at the output. 
  would you please let me know what I am doing wrong?

  Alireza,

itkLabelStatisticsImageFilter computes a number of quantities for labels in an image. One of them is the region covered by the label. The center is easiliy calculated from this.

Again you can use my contribution to ITK http://voxel.jouy.inra.fr/ 
darcsweb/darcsweb.cgi?r=binaryAttributeMorphology;a=summary to get 
this info, or an older one I will NOT submit to the insight journal, 
but which may be a little easiest to use http://voxel.jouy.inra.fr/ 
darcsweb/darcsweb.cgi?r=labelShape;a=summary .
I don't know any other way to get those infos.
