We've just noticed that the Astra SDK applies some sort of smoothing filtering to the skeleton points.
It's noticeable when you overlay the skeleton over the depth frame, if you move your arms very fast, we noticed there's a lag between the depth image and the skeleton points.
Among other things, we use skeleton tracking to measure certain features such as velocity. These kind of measurements cannot be done over a smoothed skeleton.
Is there a way to disable the smoothing?
If such an option doesn't exist, please, include it in the next SDK.
