Is there a way to calculate the determinant of the Jacobian to see whether the used B-spline transformation is volume preserving? What alternative methods can I use to ensure that there is no shrinkag…

* sames smoothness as natural splines, not interpolating (only approximating) but local control
* "B" stands for "basis". Why?
* control points are called "de Boor" control points?
* curve lies wit…

The first issue was that you write "Control points are user-defined, pre-specified points through which the curve must pass."
From my understanding (which largely stems from Freya Holmers video), cur…

I've added a button to the FP tab which sets all coefficients sliders to the optimal fit ( d624f0a9d86abc40f219a4ee75766c6533399cf3 ). Please review the functionality etc. because implementing this in…

Inspired by https://typedrawers.com/discussion/4052/using-b-splines-to-draw-italics#latest I thought I'd propose that :)

Hi, I have registered some images with the following parameter map vector :
```
elsx = sitk.ElastixImageFilter()
pmap = sitk.GetDefaultParameterMap('bspline')
elsx.SetParameterMap(pmap)
```

Interfax is a very nice package. However, if it is included in the code wrapped in jax.grad, it is about 10x slower than my simple cubic spline interpolation. Interpolation itself is not significant…
