[Insight-users] digital contour smoothing?

[Nicholas Tustison]

Hi Dean,

The following IJ submission might be of interest to you.  It performs  
B-spline approximation for curves (open,closed) as well as  
approximation of higher order B-spline objects.

It was recently transferred to the Review directory.

Good luck,
Nick
