Oh okay. I'll read it. Also, Can you please explain why you have divided pitch, roll, and yaw by 180 here
from head-pose-estimation.
I think a lot of experiments are required before we make this decision. Those angles are not very accurate as they are rough estimation from the face landmarks and a general 3D model. Higher value means larger pose, but it is up to the application to set the threshold of these values. Also, nodding, is a series of head movement and brings in another variable time. I currently do not have a good idea of how to define nod. Sorry about that.

@youjinChung Yes, if I still remember it right.

The OpenCV documentation had provided a really good explanation of this topic here:
https://docs.opencv.org/4.4.0/d9/d0c/group__calib3d.html
Pay attention to the chapter: Detailed Description
from head-pose-estimation.
Also, what research paper have you used? I wanted to go through that and understand how the values of pitch and roll work if that makes sense.

The angles are normalized before saving. What do you mean "how the values of pitch and roll work"? I don’t get it.

"How the values of pitch and roll work" --- Let me explain my question. I mean to say when do we consider a head to make a significant movement?
For example- Let say, we get value of roll to be 5 degrees at a time "t." Now is that 5 degrees enough to make a statement saying that head nodded towards the left side? If the value of roll is 20 degrees then it's a significant difference and we can consider that head tilted to the left, but should insignificant angles like 5-10 degrees should mean the same?

No problem! Thanks a lot for replying!

Hello @yinguobing,
does that mean actual degrees are the ones before normalized?
