[Insight-users] Results of itkCurvesLevelSetImageFilter

[Pingkun Yan]

Hi Luis,

Thank you for your reply. Actually, I applied the Sigmoid of the Gradient 
Magnitude on the "test.png" to get feature image. Then I used FastMarching 
to generate an initial circle as the test example.

Thanks!

Pingkun.
