How to detect landmarks of a face including forehead?

Question

This tutorial teaches how to detect landmarks of a face.

Here, there are no landmarks for the forehead. What can I do so that the landmarks also detect the forehead?

Answer 1

Forehead is not "re;iable" part of face, it's often being covered by hairs.. By the same reason ears are not included too in that 68-points dlib model. So, you can either create your own model or use, for example, Mediapipe Mesh.
