I am currently searching for a solution for the following problem:
A certain pointcloud (planar) is given. I want to find the contour lines, e.g. when the point cloud looses density and later connect these areas with a polyline (blue in picture).
I therefore need to extract these contour points and then connect them. A way to find the contour points would be to etract all points, which dont have a certain amount of neighbours, but I am not sure about this approach.
