I'm wondering if there's an easy way of fitting a BSpline (calculating the node coefficients) to a dense vector deformation field? For example, I have a 3D VDF and I want to represent the transformation it as a 3D BSpline?<br>
<br>
Or even better, say I have a 4D VDF (3D + time) and I want to represent the transformation between time=0 and time=N as a 3D BSpline?<br>
<br>
Thanks,<br>
Constantine<br>
