Performance is super slow for me

[eannkst]

Hi, i tried your repository and setting it up worked very well :) also face detection is great!
But i have a problem, the performance is super slow for me, it is far away from real-time estimation ...
Do you have an idea why i have this problem ? I'm using Intel i7with 32 GB Ram and normal webcam in 720p.
Thanks :)

Hello, great to know that you like the project and it works for your need. I can think of one overhead that can cause slower fps, face detection. Currently, it's using dlib cnn face detector. If you need faster fps you can use a GPU to run inference or you can use hog based detector tweaking

HeadPoseEstimation/head_pose_from_webcam.py

Line 46 in b1cf55b

faces = face_recognition.face_locations(img, model="cnn")

to,
faces = face_recognition.face_locations(img, model="hog")
hope this helps.

We should pin this issue so that others can also apply this solution. I am also working on some less computationally heavy face detection model.
