[Insight-users] How to select seed points from an image

[Luis Ibanez]

Hi Raghu,


The seed points that are provided as examples in the
ITK Software Guide will *not* work for any other dataset.


In order to select proper seed points for your dataset,
you will need to use some visualization tool.


You can use:

   * ImageViewer from InsightApplications

or

   * SNAP (http://www.itksnap.org)

or

   * SLICER  (www.slicer.org)


If you are building a full application, then you may
want to combine ITK with

    * VTK  for visualization

and

    * A GUI library such as
    ** Qt
    ** FLTK
    ** wxWindows
    ** KWWidgets


 From the visualization front of your GUI application
you will capture seed points to pass to the ITK filters.


See for example the source code of


     InsightApplications/LiverTumorSegmentation

or

     InsightApplications/RegionGrowingSegmentation

or

     InsightApplications/FastMarchingLevelSet



   Regards,


       Luis
