Head pose estimation

[janglinko-dac]

Hello, thanks for great work!

I have a little out of the topic question. I've seen 4 ways of estimating head pose in your repo. Do you have an idea, which one is the most accurate?

Best,
Jan

Hi, @janglinko-dac
Hmm, that's a difficult question to answer, but I'd recommend using face_alignment_sfd if the speed doesn't matter.
Errors in head pose estimation can be caused by errors in landmark estimation or errors in 3D model fitting, etc., but I think the former is relatively small with the method. I think MediaPipe is also good, but as it's a model mainly targeted at selfie images, it doesn't work well with different kinds of images.
