Is there a known shape analysis technique to sample points of a not necessarily naked human body mesh (more specifically the head part).

The goal would be to randomly sample (uniform distribution) vertices of the head part of the mesh and do some PCA analysis on those points. I know in the ML literature there're techniques to reconstruct human body etc, but I wonder if there's maybe a technique which is not ML based for this specific problem.

  • $\begingroup$ I think you got what I want to sample (i.e. vertices on the head). My first approach would have been detecting features on the mesh (not sure which feature detector though). Some of those features would probably be around region of interest (maybe nose? even that would suffice), I can probably then cluster based on coordinates. $\endgroup$ – user8469759 Mar 29 at 18:07
