[Insight-users] NonUniformBSpline vnl_svd error

[Nick Tustison]

Hi Dennis,

I don't know if you'd be interested but I recently wrote a B-spline
data approximation filter that is meant to be included in ITK---I
just haven't gotten around to submitting it yet.  It's
multidimensional, hierarchical, and arbitrary order but uniform.  I
am presenting it at the MIAR conference in a week or so.  It is based
on the two-dimensional algorithm of Lee et al. (citation below).

Let me know,
Nick Tustison
