How to estimate face pose from 5 face landmarks in dlib ?

Question

I saw recently the 5 point landmarking model from dlib: https://github.com/davisking/dlib-models
I am instereing to use it to pose estimation, but I do not find the function in dlib that perform it.
My question does it exist in dlib (C++, Python)?
If not, could you suggest efficient and small time consuming pose estimation algorithm and/or open sources from 5 point that are provided by dlib ?
Thanks

OpenCV has a python wrapper so you can use it directly in your code.
