[Insight-users] contributions to insight applications

[Luis Ibanez]

Hi Lino,

Thanks a lot for contributing your code to ITK.

We incorporated your changes of the application

     ThresholdSegmentationLevelSetFltkGui

and in the SliceViewer.h file in

     InsightApplications/Auxiliary/FltkImageViewer

We are trying now the SquareCornersPointSelection
application.


    Regards,


      Luis
