Hi all,
I have two questions related to the same shape description plugin:

  1. What is the theoretical/mathematical background of shape parameter “contour temperature”. I am trying to find documentation but using this exact same wording is not helping. Any references on the rationale of this parameter formula definition and relation to fractal dimension are welcome.

  2. What is the geometrical / algorithm approach used for Convex Hull estimation in this plugin?

I assume the best person to contact is the developer himself, Thorsten Wagner… but in case he doesn’t respond, any feedback would be helpful.

Thanks!
Ary Rupp
