comment How do I create a triangulated surface from points?
I successfully used your code to generate alpha shapes for point sets. What is the name of the algorithm your used in the implementation? Is there a publication/work that can be cited for the algorithm/implementation? Thanks in advance!

comment How can I smooth a 3D surface generated by RegionBoundary?
Thanks for the updated answer. I am still wondering a little what parameter makes sense to use. I just checked with 25 which gives me somehow reasonable results for many of my datasets, but for some strange artefacts start to occur (probably overfitting as hYPtenuser pointed out).

comment How can I smooth a 3D surface generated by RegionBoundary?
You mean running the smoothing several times and updating mc in each round? I tried some values for MaxPlotPoints. 25 seems to be a good compromise... Would be nice if you would add the info to the answer :)

comment How can I smooth a 3D surface generated by RegionBoundary?
Really nice approach, thanks very much! :) Exactly what I was looking for! If it is possible to get the BSplineFunction running, this would also be nice, but the current smoothing already is what I need.

I never heard of RepeatedTiming. Thanks for that ;)

I just inserted it as a link to not confuse the question too much.

comment Efficient way to perform local Otsu thresholding on image
Thanks Silvia for this interesting approach. The problem with the CurvatureFlowFilter is that I also have objects in the image that are not circular. The structure of those gets distorted by the filter. As I said, I know about LocalAdaptiveBinarize, but local Otsu gives in many cases much better results (I tried this on images with ImageJ). That is why I am really looking for a implementation of it in Mathematica.
