Temporal decoupling of landmarks on rapid movements

[mikelkel26]

During rapid movements, I noticed significant temporal discrepancies in certain landmarks. For example, during a squat, the landmarks associated with the feet or hips shift downward as if the model were predicting a "fall."
I assume this is partly due to the fact that behind the scenes, the model uses Kalman filters to make predictions? This is particularly noticeable at low FPS.

My question is: is there a way to improve filtering, or do you have any solutions for this problem?

Thanks!

Hi @mikelkel26,

Thanks for raising the issue, it would be really helpful if you could share a sample code that i can reproduce it from my end to get more insights, or else give this a try and let me know how it went for you.

Hi @HarishPermal,
I tried with the code you shared with me and also with the code given as an exemple here. When movements become explosive, it seems that landmarks are “carried away” by the movement and become detached.
