How to measure curve distance along irregular 3D surface (i.e: human face)?
Posted on 2006-05-11
I would like to conduct 3D curve distance measurement along the surface of human face. For example, I wish to measure the distance between forehead and chin along the human face. The application will be like this, I plot three points respectively at forehead, nose and chin, I would like to know the approximate distance between these points along the human face.
From what I know, besides "geodesic distance", is there any other algorithm that can describe the curve distance along the surface? Hope to get some idea/ suggestions for this. Thank you..
