values and units of features
Closed this issue · 3 comments
What's the unit of Δpoint? Is it presented as number of pixels? If so, may I ask why it is not normalized by the width and height of the video? I believe it will be more robust if it is irrelevant to the size of the video.
And I assume that the units of angle and Δangle are degrees but not rads. Is that correct?
Thank you for your interest in this repo.

It is the distance in 2D position. (From the previous postion to the current position)

It just didn't occur to me. I agree with your idea. I think it's also a good idea to normalize with each person's height.
And I assume that the units of angle and Δangle are degrees but not rads. Is that correct?
Yes, it is degree.
