Create a head pose estimator that can tell where the head is facing in degrees using Python and OpenCV with this tutorial.

Head pose estimation is a challenging problem in computer vision because of the various steps required to solve it. Firstly, we need to locate the face in the frame and then the various facial landmarks. Now, recognizing the face seems a trivial task in this day and that is true with faces facing the camera. The problem arises when the face is at an angle. Add to that some facial landmarks are not visible due to the movement of the head. After this, we need to convert the points to 3D coordinates to find the inclination. Sounds like a lot of work? Don’t worry we will go step by step and refer two great resources that will make our work a lot easier.
