[Insight-users] Re: Which Segmentation algorithm can fulfill this task?

[Luis Ibanez]

HI Sotiris,

You may want to try the Hough Circle detection,

http://www.itk.org/Insight/Doxygen/html/classitk_1_1HoughTransform2DCirclesImageFilter.html

in particular if you don't want to require the
user to provide seed points for the segmentation.


   Regards,


      Luis
