Thanks for your quick response and sorry for forgetting adding the link to the paper. I just updated the post and added a link to the paper. It is a popular paper by Unser. I am planning to study it and try to create a notebook tutorial out of it.
The notebook example you added looks interesting but I think it is about image registration. For now, I am interested to know:
- how to compute the B-Spline control points of an image?
- how to use these control points to re-create the image?
- how to get the image derivative using the B-spline representation?
