[Insight-users] About seed points of Level set filters

[Luis Ibanez]

Hi Rashed,

Seed points passed to FastMarching are indicated using
image index coordinates, not physical point coordinates.


   What are you using for visualizing your images ?


Your perception of "location" is derived from the
software that you are using for visualization.

You may want to use use the ImageViewer application
distributed in

      InsightApplications/ImageViewer

You can download a binary version for Windows from

http://public.kitware.com/pub/itk/InsightApplicationsBin/


    Regards,


        Luis
