Machine learning on coordinates of otolith shape

Machine Learning and Modeling
1

Hello Community,
With the ReadSTL method I got an object (dataset) with 3 comluns (x,y,z) which are the coordinates of the shape's contour, just like that :
image <- readSTL("image.stl",ascii = FALSE, plot = FALSE)
Now want to extract features from this object : length, width, height, ...
Besides this, I'm looking for new features so as to build a rich dataset for machine learning
I cheked a lot about elliptic fourier descriptors (coeffs) but I can't find its implementation on R
Any help or idea to find a good feature !
Thanks in advance

Have you looked at the shapeR package?

Yes, since it's 3D shapes that I'm dealing with, it's little useful
