Is there is some reference values for these points to compare against?
Could get rotation by rotating 2 and 14 until they are in same y coordinates.
Not really have idea how to get scale. As relations will be different between faces.
And I know its stupid questions, but I only use faceswap just to extract faces to use in my program that does transformation.
Would like it to be able to add them back.
Well thanks for help. It seems I found function that transform landmarks to cut face. Will try to find point where it save to json so I can have originals and transformed. That should be all I need.
