[Insight-users] Results of itkCurvesLevelSetImageFilter

[Luis Ibanez]

Hi Pingkun,

Thanks for the clarification.

Please post to the list the following:

1) The speed (feature) image that you passed to the Curves filter.

2) The "circle" image that you generated with FastMarching.

3) The parameter setting that you select when running the Curves
    filter (eg. max number of iterations, max RMS error. etc).

4) The number of iterations that the filter actually used by
    the time it stopped.


Thanks


     Luis
