When is a Spline filter appropriate ?

[[Da...]]

I really only deal with circles and cylinders, so I use Gaussian filter settings on pretty much everything. When is a Spline filter appropriate and what is the difference from Gauss ?

Use spline for open curves.


Gauss and Spline work almost identically for closed loops such as a circle or something. Gauss is not recommended for open ended loops, e.g. lines or curves.

If you're German though you never use anything other than Gauss.

I remember that thread and your graphs were very eye opening. Just another reason why I think you should always check your unfiltered data first. Not that I needed anymore confirmation bias on that topic.
