Mobility vs Immobility

Hey folks,

I’m currently working on the analysis of my videos using DLC. Among other measurements, I’m also interested in mobility vs immobility of my labels. However, considering slight flickering between frames, how do you usually cope with this ?
How would you set a threshold for mobility/immobility?

So far, I calculated the instantaneous velocity vectors of my labels’ position.

Thanks for you help,


Lots of ways, you could calculate a distribution of jittering and then call it mobile if a point falls outside of this distribution… [You can also do some filtering first to lower jittering]
